[Asterisk-Users] DTMF Debug

[Andrei Koulik]

Hello,

 The Asterisk server is configured to accept calls through h323 net.
 When calls is came from cisco pstn gate then DTMF tone not
 recognized, but when from other h323 endpoint then all work fine.

 I thought the cisco does't send DTMF event but in rtp dump I saw
 strange packet where DTMF should be:

RTP Packet:  Size: 36 Version: 2 Padding: FALSE Extension: FALSE marker: FALSE
   timestamp: 476982374Payload: 4 SeqNumber: 19447 CSRC count: 0 SSRC: 94351557
RTP Packet:  Size: 136 Version: 2 Padding: FALSE Extension: FALSE marker: TRUE
   timestamp: 94351557 Payload: 200 SeqNumber: 12 CSRC count: 0 SSRC: 3283075717
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
RTP Packet:  Size: 36 Version: 2 Padding: FALSE Extension: FALSE marker: FALSE
   timestamp: 476982614 Payload: 4 SeqNumber: 19448 CSRC count: 0 SSRC: 94351557

   
How can I debug this issues ?
How dtmf transferred and recognized ?

PS:
 g723 codec used without vad/cng support but on other devices this
 feature is on.
