Hello list,

I'm having DTMF-troubles with a Snom phone. I want to know if it's the Snom or Asterisk that makes the trouble.


I'm playing a prompt, then make a choice for "2" :

[Jan 5 17:06:38] VERBOSE[29172] file.c: [Jan 5 17:06:38] -- <SIP/test1-00000701> Playing '/var/lib/asterisk/sounds/vprompts/109001/prompt5040.slin'
(language 'nl')
[Jan 5 17:06:39] VERBOSE[29172] pbx.c: [Jan 5 17:06:39] -- Executing [...@sub-routing:52] WaitExten("SIP/test1-00000701", "15") in new stack *[Jan 5 17:06:41] DTMF[29172] channel.c: DTMF begin '2' received on SIP/test1-00000701 [Jan 5 17:06:41] DTMF[29172] channel.c: DTMF begin ignored '2' on SIP/test1-00000701 [Jan 5 17:06:41] DTMF[29172] channel.c: DTMF end '2' received on SIP/test1-00000701, duration 160 ms [Jan 5 17:06:41] DTMF[29172] channel.c: DTMF end passthrough '2' on SIP/test1-00000701*

What follows is a prompt again, and it automatically chooses option 2 :

[Jan 5 17:06:41] VERBOSE[29172] file.c: [Jan 5 17:06:41] -- <SIP/test1-00000701> Playing '/var/lib/asterisk/sounds/vprompts/109001/prompt5041.slin' (language 'nl') *[Jan 5 17:06:41] DTMF[29172] channel.c: DTMF end '2' received on SIP/test1-00000701, duration 160 ms [Jan 5 17:06:41] DTMF[29172] channel.c: DTMF end passthrough '2' on SIP/test1-00000701*

Even without pressing "2" on the Snom phone, option 2 is chosen in the menu.


The above is different when I do the same with a Grandstream device :

[Jan 5 17:14:15] VERBOSE[29384] file.c: [Jan 5 17:14:15] -- <SIP/test6-00000714> Playing '/var/lib/asterisk/sounds/vprompts/109001/prompt5040.slin' (

Here I explicitly chose option "2" by pressing on button "2".

What is going on with the Snom ? There is a difference in duration (160ms vs 100ms). Is that the problem ??


Kind regards,
Jonas.
