Sangoma and DTMF

[AsteriT]

Hello Forum, i need help.
I'm trying to set up Vicidial to talk via DTMF with an IVR system.
If I use app_conference it works well, but unfortunately asterisk crashes after a while.

If I use MeetMe, the IVR don't recognizes the DTMF tones, I think because of timing. I tried to use an X100P clone and it works, but not always.

I bought one Sangoma A102u (I'm using the E1 line of Italian Telco), but it didn't work, IVR doesn't recognize tones. I don't know how to set timing on Sangoma's cards.

Follow my zaptel.conf, zapata.conf and wanpipe*:

Any help will be appreciated...

Are you using a channelbank for your agents?

If you use VOIP of any kind, then DTMF will not pass through meetme. I plan on trying to fix that some time in the future, but meetme is not as easy to modify as app_conference.

[AsteriT]

Thank you for reply.

Actually I'm using only VoIP (SIP) to connect the clients to Asterisk, they are in the same LAN. But I supposed that using the SEND button on the Vicidial Web Client, DTMF wouldn't pass through meetme. I didn't use dtmf directly on the SjPhone, but always pressing the send button. Indeed, using X100p for timing the dtmf were recognized from IVR.

Could I use Sangoma and X100p together and use X100p for timing?

[mflorell]

That is very odd, I've never had that problem with Sangoma cards before, I suppose you could try it with an X100P and see if it will work for you.

[AsteriT]

I tried an X100p and it worked, not perfectly but better than Sangoma.

I can't remove Sangoma, becouse I need it for E1 pri line. How I should configure zaptel.conf and other files to make Sangoma and x100p work together, and make MeetMe use the timer from x100p rather than Sangoma?

(I'm using CentOS, 2.6.9-34.ELsmp, Asterisk rel. 1.2.7.1, Vicidial 2.0.2)

[mflorell]

I think that the order of the cards on the motherboard(closer to the CPU is first) and the order in zapata and zaptel conf files should probably do it. As for guaranteeing the timer is from the X100P, no idea how you would check it.
