Re: [Asterisk-Users] TDM Fax Problems

[Bruce Reeves]

Thanks Damon, I have now turned off all echo cancelation on both the lines coming in for fax and the channels to the channel bank that have fax modems/machines. The fax is clearer, but not as clear as it was prior to *. I have an error showing up of  WARNING[2465]: chan_zap.c:3925 zt_handle_event: Ring/Off-hook in strange state 6 on channel 55 when the call is bridged between the fax modem on 6 and the T-1 on 55, or any combination of ports. Are there any other solutions or possible causes?

Turn off echo can for those calls.

I am running into errors in faxes received by my * server that I route to fax machines on a channel bank. I have a channelized T-1 coming in and I take certain channels and transfer them to channels on my channel bank. The T-1 and channel bank are on a Sangoma A104D 4 port with echo canceling. The faxes tend to have problems with sections of the transmission getting garbled or lost. Does anyone have any information on why this might be happening or how to fix it?
