I have Asterisk 22.214.171.124 (from source), with dahdi_linux & tools 126.96.36.199. I have a TDM422P rev.E/F (I beleive)
I am trying to get this working with OSLEC 0.2.
I have followed the instructions from the OSLEC site, but I am not getting any echo cancellation working. Asterisk runs fine, and I can make and receive calls, but they sometimes have an echo and I am trying to fix this.
In /var/log/asterisk/messages, I get:
chan_dahdi.c: Unable to enable echo cancellation on channel 3 (No such device)
I have been surfing all over the web to try and find a solution to this, but to no avail. I cannot get simple information such as:
- What device this is referring to?
- Is this a device which is made available by 1) Asterisk 2) Dahdi 3) OSLEC ?
I know that when I do Dahdi_Cfg, it works correctly and reports that channel 1 is configured for OSLEC.
But anytime a call is initiated, the above message appears in the log.
Can someone help me, or at least point me in the right direction?
