In order to install the b410p drivers one simply needs to type: `make b410p` The mISDN drivers will be downloaded and installed automatically. Then you will need to run `/etc/init.d/misdn-init config` and then configure the /etc/misdn-init.conf in accordance with your desired port configuration. To enable hardware echo cancellation, make sure that the line "dsp_hwechocan=1" is on in your /etc/misdn-init.conf. From there on, look to asterisk to configuration. --- Matthew Fredrickson
