The echo canceller algorithms aren't doing anything. We get extreme echo during the conversation, it appears even before the call connects, the echo is there... This only happens with SIP to/from WCFXO (analog POTS). Looking at the Zaptel configuration: /etc/asterisk/zapata.conf: echocancel=yes echocancelwhenbridged=yes rxgain=0.8 txgain=0.8 (although none of the above options seem to make any difference). Is there any debugging we can turn on to see what the problem may be, this definitely will hurt production of this environment.

[Asterisk-Users] Very bad echo (appears that...)
Hi, Uncomment the following line in the makefile in /usr/src/zaptel KFLAGS+=-DAGGRESSIVE_SUPPRESSOR Do a make clean install in this directory and reload wcfxo driver (rmmod and then modprobe). Try again and see if there is any improvement.

Oh, I forgot to say, zaptel/wcfxo is compiled with: KFLAGS+=-DECHO_CAN_MARK2 KFLAGS+=-DAGGRESSIVE_SUPPRESSOR (and, Brian, my jack is wired correct..) -----Original Message----- From: Lenny Tropiano [mailto:lenny@voiping.com] On Behalf Of Asterisk PBX Sent: Sunday, September 21, 2003 5:02 PM To: 'Asterisk-users@lists.digium.com' Subject: Very bad echo (appears that...)

My partner found it!! Problem solved... The error was a syntax error in the zapata.conf channel=1 Should have been written as: channel=>1
Just on a side note can you please put a realname in your name field on your email client. Everytime I see "Asterisk PBX" I think gee more voicemail. bwk On Sun, 21 Sep 2003, Asterisk PBX wrote:> My partner found it!! > > Problem solved... > > The error was a syntax error in the zapata.conf > > channel=1 > > Should have been written as: > > channel=>1 > > > > _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com > http://lists.digium.com/mailman/listinfo/asterisk-users >

[Asterisk-Users] RE: Very bad echo (appears that...)
You are kidding,I hope. This typo would manifest itself as an echo problem? May be the parser needs to put out a warning of some kind. That is my 2cents.
