Bob, I should have added that I have disabled hardware EC on the T1 ports.
Here is a sample of my zapata.conf -- channels 1-23 are my incoming PRI. This PRI handles both Voice AND FAX calls. Having the hardware EC disabled makes for poor voice communications, and im looking for a way to enable/disable EC per the call type. I understand that "echoncancelwhenbridged" and Zapata should be telling my A104d to enable/disable HWEC automatically. Channel 25 is the first FXS port on my Rhino CB. It has a FAX directly attached to it. [channels] language = en switchtype = national signalling = pri_cpe pridialplan = national prilocaldialplan = national faxdetect = both echotraining = no echocancel = 256 echocancelwhenbridged = no relaxdtmf = yes overlapdial = no usecallingpres = yes amaflags = default context = default group = 1 channel => 1-23 signalling = fxo_ls faxdetect = both echotraining = no echocancel = no echocancelwhenbridged = no relaxdtmf = yes context = default callerid = "FAX" <1112222> channel => 25 Thanks for your assistance everyone! --- On Fri, 9/5/08, Bob Pierce <[EMAIL PROTECTED]> wrote: From: Bob Pierce <[EMAIL PROTECTED]> Subject: Re: [asterisk-users] FAX over T1 Question To: "Asterisk Users Mailing List - Non-Commercial Discussion" <asterisk-users@lists.digium.com> Date: Friday, September 5, 2008, 4:43 PM On Fri, 2008-09-05 at 09:19 -0700, Amaru Netapshaak wrote: > I have a Sangoma A104d T1 card, a Rhino 24-port FXS box, and am > running > Asterisk 1.4.21.2 I think you're mostly right on this setup, but I wonder if your A104d is doing some hardware echo cancellation on these calls. If I'm not mistaken, that can mess up fax machine communications. Bob
