From fc0fecb4768d696db3324bcf6dd03325bb4cd513 Mon Sep 17 00:00:00 2001 From: Matthew Jordan Date: Thu, 17 Jul 2014 21:17:28 +0000 Subject: configs: Move sample config files into a subdirectory of configs This moves all samples configs from configs/ to configs/samples. This allows for additional sets of sample configuration files to be added in the future.

If your Asterisk is installed on a public +; IP address connected to the Internet, you will want to learn +; about the various security settings BEFORE you start +; Asterisk. +; +; Especially note the following settings: +; - allowguest (default enabled) +; - permit/deny/acl - IP address filters +; - contactpermit/contactdeny/contactacl - IP address filters for registrations +; - context - Which set of services you offer various users +; +; SIP dial strings +;----------------------------------------------------------- +; In the dialplan (extensions.conf) you can use several +; syntaxes for dialing SIP devices. +; SIP/devicename +; SIP/username@domain (SIP uri) +; SIP/username[:password[:md5secret[:authname[:transport]]]]@host[:port] +; SIP/devicename/extension +; SIP/devicename/extension/IPorHost +; SIP/username@domain//IPorHost +; +; +; Devicename +; devicename is defined as a peer in a section below. +; +; username@domain +; Call any SIP user on the Internet +; (Don't forget to enable DNS SRV records if you want to use this) +; +; devicename/extension +; If you define a SIP proxy as a peer below, you may call +; SIP/proxyhostname/user or SIP/user@proxyhostname +; where the proxyhostname is defined in a section below +; This syntax also works with ATA's with FXO ports +; +; SIP/username[:password[:md5secret[:authname]]]@host[:port] +; This form allows you to specify password or md5secret and authname +; without altering any authentication data in config. +; Examples: +; +; SIP/*98@mysipproxy +; SIP/sales:topsecret::account02@domain.com:5062 +; SIP/12345678::bc53f0ba8ceb1ded2b70e05c3f91de4f:myname@192.168.0.1 +; +; IPorHost +; The next server for this call regardless of domain/peer +; +; All of these dial strings specify the SIP request URI. +; In addition, you can specify a specific To: header by adding an +; exclamation mark after the dial string, like +; +; SIP/sales@mysipproxy!sales@edvina.net +; +; A new feature for 1.8 allows one to specify a host or IP address to use +; when routing the call. This is typically used in tandem with func_srv if +; multiple methods of reaching the same domain exist. The host or IP address +; is specified after the third slash in the dialstring. Examples: +; +; SIP/devicename/extension/IPorHost +; SIP/username@domain//IPorHost +; +; CLI Commands +; ------------------------------------------------------------- +; Useful CLI commands to check peers/users: +; sip show peers Show all SIP peers (including friends) +; sip show registry Show status of hosts we register with +; +; sip set debug on Show all SIP messages +; +; sip reload Reload configuration file +; sip show settings Show the current channel configuration +; +;------- Naming devices ------------------------------------------------------ +; +; When naming devices, make sure you understand how Asterisk matches calls +; that come in. +; 1. Asterisk checks the SIP From: address username and matches against +; names of devices with type=user +; The name is the text between square brackets [name] +; 2. Asterisk checks the From: addres and matches the list of devices +; with a type=peer +; 3. Asterisk checks the IP address (and port number) that the INVITE +; was sent from and matches against any devices with type=peer +; +; Don't mix extensions with the names of the devices. Devices need a unique +; name. The device name is *not* used as phone numbers. Phone numbers are +; anything you declare as an extension in the dialplan (extensions.conf). +; +; When setting up trunks, make sure there's no risk that any From: username +; (caller ID) will match any of your device names, because then Asterisk +; might match the wrong device. +; +; Note: The parameter "username" is not the username and in most cases is +; not needed at all. Check below. In later releases, it's renamed +; to "defaultuser" which is a better name, since it is used in +; combination with the "defaultip" setting. +;----------------------------------------------------------------------------- + +; ** Old configuration options ** +; The "call-limit" configuation option is considered old is replaced +; by new functionality. To enable callcounters, you use the new +; "callcounter" setting (for extension states in queue and subscriptions) +; You are encouraged to use the dialplan groupcount functionality +; to enforce call limits instead of using this channel-specific method. +; You can still set limits per device in sip.conf or in a database by using +; "setvar" to set variables that can be used in the dialplan for various limits. + +[general] +context=public ; Default context for incoming calls.

Defaults to 'automon'. Works with + ; dynamic features. Feature must be usable on requesting + ; channel for it to work. Setting this value to a blank + ; will disable it. +;recordofffeature=automixmon ; Default feature to use when receiving 'Record: off' header + ; from an INFO message. Defaults to 'automon'. Works with + ; dynamic features. Feature must be usable on requesting + ; channel for it to work. Setting this value to a blank + ; will disable it. + +; With the current situation, you can do one of four things: +; a) Listen on a specific IPv4 address. Example: bindaddr=192.0.2.1 +; b) Listen on a specific IPv6 address. Example: bindaddr=2001:db8::1 +; c) Listen on the IPv4 wildcard. Example: bindaddr=0.0.0.0 +; d) Listen on the IPv4 and IPv6 wildcards. Example: bindaddr=:: +; (You can choose independently for UDP, TCP, and TLS, by specifying different values for +; "udpbindaddr", "tcpbindaddr", and "tlsbindaddr".) +; (Note that using bindaddr=:: will show only a single IPv6 socket in netstat. +; IPv4 is supported at the same time using IPv4-mapped IPv6 addresses.) +; +; You may optionally add a port number. (The default is port 5060 for UDP and TCP, 5061 +; for TLS). +; IPv4 example: bindaddr=0.0.0.0:5062 +; IPv6 example: bindaddr=[::]:5062 +; +; The address family of the bound UDP address is used to determine how Asterisk performs +; DNS lookups. In cases a) and c) above, only A records are considered. In case b), only +; AAAA records are considered. In case d), both A and AAAA records are considered. Note, +; however, that Asterisk ignores all records except the first one. In case d), when both A +; and AAAA records are available, either an A or AAAA record will be first, and which one +; depends on the operating system. On systems using glibc, AAAA records are given +; priority. + +udpbindaddr=0.0.0.0 ; IP address to bind UDP listen socket to (0.0.0.0 binds to all) + ; Optionally add a port number, 192.168.1.1:5062 (default is port 5060) + +; When a dialog is started with another SIP endpoint, the other endpoint +; should include an Allow header telling us what SIP methods the endpoint +; implements. However, some endpoints either do not include an Allow header +; or lie about what methods they implement. In the former case, Asterisk +; makes the assumption that the endpoint supports all known SIP methods. +; If you know that your SIP endpoint does not provide support for a specific +; method, then you may provide a comma-separated list of methods that your +; endpoint does not implement in the disallowed_methods option. Note that +; if your endpoint is truthful with its Allow header, then there is no need +; to set this option. This option may be set in the general section or may +; be set per endpoint. If this option is set both in the general section and +; in a peer section, then the peer setting completely overrides the general +; setting (i.e. the result is *not* the union of the two options). +; +; Note also that while Asterisk currently will parse an Allow header to learn +; what methods an endpoint supports, the only actual use for this currently +; is for determining if Asterisk may send connected line UPDATE requests and +; MESSAGE requests. Its use may be expanded in the future. +; +; disallowed_methods = UPDATE + +; +; Note that the TCP and TLS support for chan_sip is currently considered +; experimental.

Specify + ; 'ignore-context' to ignore the called context when looking + ; for the caller's channel. The default value is 'no.' Setting + ; notifycid to 'ignore-context' also causes call-pickups attempted + ; via SNOM's NOTIFY mechanism to set the context for the call pickup + ; to PICKUPMARK. +;callcounter = yes ; Enable call counters on devices. This can be set per + ; device too. + +;----------------------------------------- T.38 FAX SUPPORT ---------------------------------- +; +; This setting is available in the [general] section as well as in device configurations. +; Setting this to yes enables T.38 FAX (UDPTL) on SIP calls; it defaults to off. +; +; t38pt_udptl = yes ; Enables T.38 with FEC error correction. +; t38pt_udptl = yes,fec ; Enables T.38 with FEC error correction. +; t38pt_udptl = yes,redundancy ; Enables T.38 with redundancy error correction. +; t38pt_udptl = yes,none ; Enables T.38 with no error correction. +; +; In some cases, T.38 endpoints will provide a T38FaxMaxDatagram value (during T.38 setup) that +; is based on an incorrect interpretation of the T.38 recommendation, and results in failures +; because Asterisk does not believe it can send T.38 packets of a reasonable size to that +; endpoint (Cisco media gateways are one example of this situation). In these cases, during a +; T.38 call you will see warning messages on the console/in the logs from the Asterisk UDPTL +; stack complaining about lack of buffer space to send T.38 FAX packets. If this occurs, you +; can set an override (globally, or on a per-device basis) to make Asterisk ignore the +; T38FaxMaxDatagram value specified by the other endpoint, and use a configured value instead. +; This can be done by appending 'maxdatagram=' to the t38pt_udptl configuration option, +; like this: +; +; t38pt_udptl = yes,fec,maxdatagram=400 ; Enables T.38 with FEC error correction and overrides +; ; the other endpoint's provided value to assume we can +; ; send 400 byte T.38 FAX packets to it. +; +; FAX detection will cause the SIP channel to jump to the 'fax' extension (if it exists) +; based one or more events being detected. The events that can be detected are an incoming +; CNG tone or an incoming T.38 re-INVITE request. +; +; faxdetect = yes ; Default 'no', 'yes' enables both CNG and T.38 detection +; faxdetect = cng ; Enables only CNG detection +; faxdetect = t38 ; Enables only T.38 detection +; +;----------------------------------------- OUTBOUND SIP REGISTRATIONS ------------------------ +; Asterisk can register as a SIP user agent to a SIP proxy (provider) +; Format for the register statement is: +; register => [peer?][transport://]user[@domain][:secret[:authuser]]@host[:port][/extension][~expiry] +; +; +; +; domain is either +; - domain in DNS +; - host name in DNS +; - the name of a peer defined below or in realtime +; The domain is where you register your username, so your SIP uri you are registering to +; is username@domain +; +; If no extension is given, the 's' extension is used. The extension needs to +; be defined in extensions.conf to be able to accept calls from this SIP proxy +; (provider). +; +; A similar effect can be achieved by adding a "callbackextension" option in a peer section. +; this is equivalent to having the following line in the general section: +; +; register => username:secret@host/callbackextension +; +; and more readable because you don't have to write the parameters in two places +; (note that the "port" is ignored - this is a bug that should be fixed). +; +; Note that a register= line doesn't mean that we will match the incoming call in any +; other way than described above. If you want to control where the call enters your +; dialplan, which context, you want to define a peer with the hostname of the provider's +; server. If the provider has multiple servers to place calls to your system, you need +; a peer for each server. +; +; Beginning with Asterisk version 1.6.2, the "user" portion of the register line may +; contain a port number. Since the logical separator between a host and port number is a +; ':' character, and this character is already used to separate between the optional "secret" +; and "authuser" portions of the line, there is a bit of a hoop to jump through if you wish +; to use a port here. That is, you must explicitly provide a "secret" and "authuser" even if +; they are blank. See the third example below for an illustration. +; +; +; Examples: +; +;register => 1234:password@mysipprovider.com +; +; This will pass incoming calls to the 's' extension +; +; +;register => 2345:password@sip_proxy/1234 +; +; Register 2345 at sip provider 'sip_proxy'. Calls from this provider +; connect to local extension 1234 in extensions.conf, default context, +; unless you configure a [sip_proxy] section below, and configure a +; context. +; Tip 1: Avoid assigning hostname to a sip.conf section like [provider.com] +; Tip 2: Use separate inbound and outbound sections for SIP providers +; (instead of type=friend) if you have calls in both directions +; +;register => 3456@mydomain:5082::@mysipprovider.com +; +; Note that in this example, the optional authuser and secret portions have +; been left blank because we have specified a port in the user section +; +;register => tls://username:xxxxxx@sip-tls-proxy.example.org +; +; The 'transport' part defaults to 'udp' but may also be 'tcp', 'tls', 'ws', or 'wss'. +; Using 'udp://' explicitly is also useful in case the username part +; contains a '/' ('user/name'). + +;registertimeout=20 ; retry registration calls every 20 seconds (default) +;registerattempts=10 ; Number of registration attempts before we give up + ; 0 = continue forever, hammering the other server + ; until it accepts the registration + ; Default is 0 tries, continue forever +;register_retry_403=yes ; Treat 403 responses to registrations as if they were + ; 401 responses and continue retrying according to normal + ; retry rules. + +;----------------------------------------- OUTBOUND MWI SUBSCRIPTIONS ------------------------- +; Asterisk can subscribe to receive the MWI from another SIP server and store it locally for retrieval +; by other phones. At this time, you can only subscribe using UDP as the transport. +; Format for the mwi register statement is: +; mwi => user[:secret[:authuser]]@host[:port]/mailbox +; +; Examples: +;mwi => 1234:password@mysipprovider.com/1234 +;mwi => 1234:password@myportprovider.com:6969/1234 +;mwi => 1234:password:authuser@myauthprovider.com/1234 +;mwi => 1234:password:authuser@myauthportprovider.com:6969/1234 +; +; MWI received will be stored in the 1234 mailbox of the SIP_Remote context. +; It can be used by other phones by following the below: +; mailbox=1234@SIP_Remote +;----------------------------------------- NAT SUPPORT ------------------------ +; +; WARNING: SIP operation behind a NAT is tricky and you really need +; to read and understand well the following section. +; +; When Asterisk is behind a NAT device, the "local" address (and port) that +; a socket is bound to has different values when seen from the inside or +; from the outside of the NATted network. Unfortunately this address must +; be communicated to the outside (e.g. in SIP and SDP messages), and in +; order to determine the correct value Asterisk needs to know: +; +; + whether it is talking to someone "inside" or "outside" of the NATted network. +; This is configured by assigning the "localnet" parameter with a list +; of network addresses that are considered "inside" of the NATted network. +; IF LOCALNET IS NOT SET, THE EXTERNAL ADDRESS WILL NOT BE SET CORRECTLY. +; Multiple entries are allowed, e.g. a reasonable set is the following: +; +; localnet=192.168.0.0/255.255.0.0 ; RFC 1918 addresses +; localnet=10.0.0.0/255.0.0.0 ; Also RFC1918 +; localnet=172.16.0.0/12 ; Another RFC1918 with CIDR notation +; localnet=169.254.0.0/255.255.0.0 ; Zero conf local network +; +; + the "externally visible" address and port number to be used when talking +; to a host outside the NAT. This information is derived by one of the +; following (mutually exclusive) config file parameters: +; +; a. "externaddr = hostname[:port]" specifies a static address[:port] to +; be used in SIP and SDP messages. +; The hostname is looked up only once, when [re]loading sip.conf . +; If a port number is not present, use the port specified in the "udpbindaddr" +; (which is not guaranteed to work correctly, because a NAT box might remap the +; port number as well as the address). +; This approach can be useful if you have a NAT device where you can +; configure the mapping statically. Examples: +; +; externaddr = 12.34.56.78 ; use this address. +; externaddr = 12.34.56.78:9900 ; use this address and port. +; externaddr = mynat.my.org:12600 ; Public address of my nat box. +; externtcpport = 9900 ; The externally mapped tcp port, when Asterisk is behind a static NAT or PAT. +; ; externtcpport will default to the externaddr or externhost port if either one is set. +; externtlsport = 12600 ; The externally mapped tls port, when Asterisk is behind a static NAT or PAT. +; ; externtlsport port will default to the RFC designated port of 5061. +; +; b. "externhost = hostname[:port]" is similar to "externaddr" except +; that the hostname is looked up every "externrefresh" seconds +; (default 10s). This can be useful when your NAT device lets you choose +; the port mapping, but the IP address is dynamic. +; Beware, you might suffer from service disruption when the name server +; resolution fails. Examples: +; +; externhost=foo.dyndns.net ; refreshed periodically +; externrefresh=180 ; change the refresh interval +; +; Note that at the moment all these mechanism work only for the SIP socket. +; The IP address discovered with externaddr/externhost is reused for +; media sessions as well, but the port numbers are not remapped so you +; may still experience problems. +; +; NOTE 1: in some cases, NAT boxes will use different port numbers in +; the internal<->external mapping. In these cases, the "externaddr" and +; "externhost" might not help you configure addresses properly. +; +; NOTE 2: when using "externaddr" or "externhost", the address part is +; also used as the external address for media sessions. Thus, the port +; information in the SDP may be wrong! +; +; In addition to the above, Asterisk has an additional "nat" parameter to +; address NAT-related issues in incoming SIP or media sessions. +; In particular, depending on the 'nat= ' settings described below, Asterisk +; may override the address/port information specified in the SIP/SDP messages, +; and use the information (sender address) supplied by the network stack instead. +; However, this is only useful if the external traffic can reach us. +; The following settings are allowed (both globally and in individual sections): +; +; nat = no ; Do no special NAT handling other than RFC3581 +; nat = force_rport ; Pretend there was an rport parameter even if there wasn't +; nat = comedia ; Send media to the port Asterisk received it from regardless +; ; of where the SDP says to send it. +; nat = auto_force_rport ; Set the force_rport option if Asterisk detects NAT (default) +; nat = auto_comedia ; Set the comedia option if Asterisk detects NAT +; +; The nat settings can be combined. For example, to set both force_rport and comedia +; one would set nat=force_rport,comedia. If any of the comma-separated options is 'no', +; Asterisk will ignore any other settings and set nat=no. If one of the "auto" settings +; is used in conjunction with its non-auto counterpart (nat=comedia,auto_comedia), then +; the non-auto option will be ignored. +; +; The RFC 3581-defined 'rport' parameter allows a client to request that Asterisk send +; SIP responses to it via the source IP and port from which the request originated +; instead of the address/port listed in the top-most Via header. This is useful if a +; client knows that it is behind a NAT and therefore cannot guess from what address/port +; its request will be sent. Asterisk will always honor the 'rport' parameter if it is +; sent. The force_rport setting causes Asterisk to always send responses back to the +; address/port from which it received requests; even if the other side doesn't support +; adding the 'rport' parameter. +; +; 'comedia RTP handling' refers to the technique of sending RTP to the port that the +; the other endpoint's RTP arrived from, and means 'connection-oriented media'. This is +; only partially related to RFC 4145 which was referred to as COMEDIA while it was in +; draft form. This method is used to accomodate endpoints that may be located behind +; NAT devices, and as such the address/port they tell Asterisk to send RTP packets to +; for their media streams is not the actual address/port that will be used on the nearer +; side of the NAT. +; +; IT IS IMPORTANT TO NOTE that if the nat setting in the general section differs from +; the nat setting in a peer definition, then the peer username will be discoverable +; by outside parties as Asterisk will respond to different ports for defined and +; undefined peers. For this reason it is recommended to ONLY DEFINE NAT SETTINGS IN THE +; GENERAL SECTION. Specifically, if nat=force_rport in one section and nat=no in the +; other, then valid peers with settings differing from those in the general section will +; be discoverable. +; +; In addition to these settings, Asterisk *always* uses 'symmetric RTP' mode as defined by +; RFC 4961; Asterisk will always send RTP packets from the same port number it expects +; to receive them on. +; +; The IP address used for media (audio, video, and text) in the SDP can also be overridden by using +; the media_address configuration option. This is only applicable to the general section and +; can not be set per-user or per-peer. +; +; media_address = 172.16.42.1 +; +; Through the use of the res_stun_monitor module, Asterisk has the ability to detect when the +; perceived external network address has changed. When the stun_monitor is installed and +; configured, chan_sip will renew all outbound registrations when the monitor detects any sort +; of network change has occurred. By default this option is enabled, but only takes effect once +; res_stun_monitor is configured. If res_stun_monitor is enabled and you wish to not +; generate all outbound registrations on a network change, use the option below to disable +; this feature. +; +; subscribe_network_change_event = yes ; on by default +; +; ICE/STUN/TURN usage can be enabled globally or on a per-peer basis using the icesupport +; configuration option. When set to yes ICE support is enabled. When set to no it is disabled. +; It is disabled by default. +; +; icesupport = yes + +;----------------------------------- MEDIA HANDLING -------------------------------- +; By default, Asterisk tries to re-invite media streams to an optimal path. If there's +; no reason for Asterisk to stay in the media path, the media will be redirected. +; This does not really work well in the case where Asterisk is outside and the +; clients are on the inside of a NAT. In that case, you want to set directmedia=nonat. +; +;directmedia=yes ; Asterisk by default tries to redirect the + ; RTP media stream to go directly from + ; the caller to the callee. Some devices do not + ; support this (especially if one of them is behind a NAT). + ; The default setting is YES. If you have all clients + ; behind a NAT, or for some other reason want Asterisk to + ; stay in the audio path, you may want to turn this off. + + ; This setting also affect direct RTP + ; at call setup (a new feature in 1.4 - setting up the + ; call directly between the endpoints instead of sending + ; a re-INVITE). + + ; Additionally this option does not disable all reINVITE operations. + ; It only controls Asterisk generating reINVITEs for the specific + ; purpose of setting up a direct media path. If a reINVITE is + ; needed to switch a media stream to inactive (when placed on + ; hold) or to T.38, it will still be done, regardless of this + ; setting. Note that direct T.38 is not supported. + +;directmedia=nonat ; An additional option is to allow media path redirection + ; (reinvite) but only when the peer where the media is being + ; sent is known to not be behind a NAT (as the RTP core can + ; determine it based on the apparent IP address the media + ; arrives from). + +;directmedia=update ; Yet a third option... use UPDATE for media path redirection, + ; instead of INVITE.

This means calls made from either direction won't work if +; The peer is unregistered while host=dynamic or if the host is otherise not set to +; the correct IP of the sender. +; * For entities with 'type=user': +; Asterisk users handle inbound calls only (meaning they call Asterisk, Asterisk can't +; call them) and are matched by their authorization information (authname and secret). +; Asterisk doesn't rely on their IP and will accept calls regardless of the host setting +; as long as the incoming SIP invite authorizes successfully. +; * For entities with 'type=friend': +; Asterisk will create the entity as both a friend and a peer. Asterisk will accept +; calls from friends like it would for users, requiring only that the authorization +; matches rather than the IP address. Since it is also a peer, a friend entity can +; be called as long as its IP is known to Asterisk. In the case of host=dynamic, +; this means it is necessary for the entity to register before Asterisk can call it. +; +; Use remotesecret for outbound authentication, and secret for authenticating +; inbound requests.
