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. It should use MG2 as specified in DAHDI's system.conf: #autogenerated by /usr/sbin/wancfg_dahdi do not hand edit #autogenrated on 2010-12-08 #Dahdi Channels Configurations #For detailed Dahdi options, view /etc/dahdi/system.conf.bak loadzone=us defaultzone=us #Sangoma A104 port 1 [slot:2 bus:2 span:1] <wanpipe1> span=1,1,0,esf,b8zs bchan=1-23 #dchan=24 echocanceller=mg2,1-23 hardhdlc=24 And, from chan_dahdi.conf: ;Sangoma A104 port 1 [slot:2 bus:2 span:1] <wanpipe1> switchtype=national context=ldrouted group=1 echocancel=yes signalling=pri_net channel =>1-23 Any thoughts, pointers, suggestions? The echo is horrible, please help me make it stop. :-) --Tim -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
