[asterisk-users] DTMF reception during WaitForSilence

[Steven Davison]

You last question : why are DTMF tones not audible in the recording?

WE had issues with DTMF not recording, and found it was due to the handset only sending the DTMF in data, rather than inline, as a beep... that could be your reason :)

Subject: [asterisk-users] DTMF reception during WaitForSilence

Hello,

I wrote a little AGI-Script that implements an IVR (using asterisk 1.6).
The whole conversation is recorded and at some points the caller should 
tell some information.
I detect the silence (WaitForSilence) to go to the next step in the IVR. 
Until now everything is OK, but...
some information the user gives (or speaks) is numeric... some users 
have the habit, to enter numeric
information via the phonekeypad (ergo creating dtmf-tones) but I cant 
process DTMF-Input
during "WaitForSilence".
How can I achive that both works simultaneously? I mean recording the 
spoken digits AND detecting
DTMF-Input AND detecting silence to "know", when Input has finished... 
(I want to avoid that users
have to finish their input with the pound-key...) ?

Btw.: why are the DTMF-Tones, that a user enters, not hearable in the 
recording?

Thanks for your help and hints,
Yves
