[asterisk-users] Echo Cancellation Problem - Invalid Argument?!?
Greetings folks- I'm experiencing issues with a freshly installed box. When a call comes in via PRI (Sangoma AFT-A104), I see this in my logs: [Dec 15 14:26:10] WARNING[23546] chan_dahdi.c: Unable to enable echo cancellation on channel 12 (Invalid argument) [Dec 15 14:26:10] WARNING[23546] chan_dahdi.c: Unable to enable echo cancellation on channel 8 (Invalid argument) [Dec 15 14:26:10] WARNING[23546] chan_dahdi.c: Unable to enable echo cancellation on channel 10 (Invalid argument) [Dec 15 14:26:10] WARNING[23546] chan_dahdi.c: Unable to enable echo cancellation on channel 9 (Invalid argument) Relevant components: Asterisk: Asterisk SVN-trunk-r290509 built by root @ prigw01 on a i686 running Linux on 2010-11-30 22:12:05 UTC DAHDI: dahdi-linux-complete-2.4.0+2.4.0 LibPRI: libpri-1.4.11.5 Wanpipe: wanpipe-3.5.18 Kernel: Linux prigw01 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 06:07:29 UTC 2010 i686 GNU/Linux The card does not have a hardware echo canceler.

Well, I "downgraded" this box to Asterisk 1.4.38 and all is well again. Echo cancellation works properly, no problems, no errors. I have to assume this is a bug in Asterisk 1.8.x or Wanpipe 3.5.18. --Tim ----- Original Message -----> Greetings folks- > > I'm experiencing issues with a freshly installed box.
