2009-09-14Race condition in handling writes to proslic LINEFEED register (64)Doug Bailey
The wctdm24xxp driver has a problem where a VMWI IOCTL call followed immediately by a ONHOOKTRANSFER IOCTL call will cause the ONHOOK transfer request to be dropped. This occurs if the write to the proslic's LINEFEED register for the VMWI ICTL call is not completed when the ONHOOK transfer request IOCTL is processed. I also cleaned out some magic numbers used in setting the linefeed register.

2009-08-19Ensure that dahdi_scan correctly reports VPM presence.Kevin P. Fleming
The wct4xxp driver (for the dual/quad span T1/E1 cards) and the wcte12xp driver (for the single span VoiceBus-based T1/E1 cards) did not properly update the 'devicetype' field reported by dahdi_scan when a VPM was found during the card startup process. As a result, dahdi_scan did not show that a VPM was present on the card, even if it was. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@7038 a0bf4364-ded3-4de4-8d8a-66a801d63aff

state. Check if our hookstate has been set back to the initial state, typically the result of a chanconfig, and if so, if we're an FXO port, forget our current battery state.

Adds a struct module 'owner' member to the dahdi_span structure and updates all the board drivers to set this member before registering the span. This allows the core of dahdi to maintain the reference counts on the channels itself.

2009-05-11voicebus: Update the default vpmadt032 parameters.Shaun Ruffell
Move the echo can channel parameters into a common location for both the wcte12xp and wctdm24xxp drivers that use the voicebus module. This is intended to make it clearer which differences are required between the clients. Additionally, update the default parameters to the new recommended values.

2009-05-07voicebus: Create workqueue for each vpmadt032 instance.Shaun Ruffell
Depending on the system latency, the deferred work for the vpmadt032 can take up to 200ms. This change allows each vpmadt032 to use its own workqueue, and not the global system workqueue. This prevents vpm operations from blocking the main system workqueue for extended periods. This restores the behavior to the way it was before the common vpmadt032 code was moved out of the wctdm24xxp and wcte12xp drivers.

2009-05-07voicebus: Changing default NLP type to 'suppression'.Shaun Ruffell

2009-04-29echocan: Improve interface for echo cancelers.Shaun Ruffell
Echo cancelers are now able to report if they are able to automatically disable their NLP portions in the presence of tones in the audio stream. Also, the interface is changed to allow user space to just disable the NLP portion of the echo canceler. These changes improve fax and modem handling in DAHDI.

2009-04-29voicebus: Move common vpmadt032 interface into voicebus module.Shaun Ruffell
The voicebus library was previously linked into both the wcte12xp and wctdm24xxp drivers. It is now broken out into it's own module and the common parts of the vpmadt032 interface are now located in that module to reduce duplication between the wcte12xp and wctdm24xxp drivers. git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@6527 a0bf4364-ded3-4de4-8d8a-66a801d63aff
