...ome debug information. Then, they ended up changing a line in wct4xxp.c of the zaptel branch, recompiling, and trying again. Lo and behold, calls have now begun to complete without issue. To resolve this issue, you need to find the line in wct4xxp.c that looks like the following: static int vpmdtmfsupport = 1; Change this to static int vpmdtmfsupport = 0; According to Digium support, this moves the playing of the DTMF's from hardware to software. Once that change was made, I have not had any other issues. Thanks, James James Texter wrote: So, I'm still having this problem with outb...

...Echo cancellation already on We don't have any problems with any other numbers, and the DTMF works on phones that are on our meridian system (which we currently pass through) so I know it's somewhere in our T1 lines or gateway... don't really know where to go from there.

Hi all, I am having problems detecting fax on a client site using the TE406P (card with echo cancellation module) under 1.2 and was wondering if anybody was having or has had similar problems?

I changed from a TE410P to a TE411P and fax carriers weren't detected anymore ! I have tried everything (recompile zaptel+asterisk+spandsp ; echocancel=yes/no ; rxgain=0/txgain=0 ; increase Wait() ; ...), nothing worked. The only solution that worked for me was to install and use NVFaxDetect. HTH.

Hi, I cannot make my TDM2400P (with Echo Canceller module) detect faxes. I tried with a TDM400P and it worked at 80% (20% of faxes were lost). My test conf.files are: _zapata.conf_: context = inbound faxdetect = incoming language = it musiconhold = default signalling = fxs_ks callerid = "call_or_fax" channel => 1 extensions.conf: [inbound] exten => s,1,Answer exten =>

...wo digits randomly.so now i can't use any voice menu on my box with this card. i have tried the following scenarios: - the card with / without vpm module has the same dtmf detection problem. - relaxdtmf=yes/no didn't solve the problem - toneduration=300 / 350 / 400 didn't help also. - vpmdtmfsupport=1 / 0 didn't solve again. what else could be the possible cause for this problem? please help! - paradise dove
