Incoming DTMF not recognized

juanmanuel · Posted: Thu Mar 17, 2011 2:52 pm Post subject: Incoming DTMF not recognized

1. Brekeke Product Name and version: PBX Version 2.4.7.3

2. Java version:

3. OS type and the version:

4. UA (phone), gateway or other hardware/software involved:

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html :

6. Your problem:

When PbX receives a call from a registered UA the DTMF sent are recognized by the AA, in this case the call is answered by AA and redirected to extension dialed by DTMF
But when it receives a call from one non registered UA, the DTMF are not recognized, in this case the call is answered by AA but not redirected to extension dialed by DTMF

The diference I see is that the INVITE from registered UA includes NOTIFY but the INVITE from non registered does not.

Dose this diference cause the problem?

Thanks and Best Regards

what type DTMF used by caller?
what codecs used for the call?
how about change caller DTMF as SIP INFO?
have you set [RFC2833] on at pbx/options?

Thanks for your answer

DTMF using RFC2833 at PBX as well at UA, codec G711 mu law

I have change to SIP-INFO and the result is the same.

I see at Sniffer that after the UA send the DTMF using RTP EVE, Brekeke PBX does noy send any confirmation for recieve it, as does when the UA is registered.
