[asterisk-users] Possibility to catch DTMF when 2 users are in a conversation

[Antoine Fressancourt]

I will sum up the results of my investigations :
- When canreinvite is set to "yes", I manage to make a video call between
the 2 parties, when I emit a DTMF signal, it triggers the playback of a
sound clip correctly, but I can't playback a video clip.
- When canreinvite is set to "no", The DTMF I emit is not detected by
Asterisk, although I see the SIP INFO message in the SIP debug messages of
Asterisk.

I copy in line the relevant abstracts of my configuration files :

-- sip.conf --

[8160]
type=friend
username=8160
secret=******
host=dynamic
context=default
disallow=all
allow=ulaw
allow=h263
dtmfmode=info
canreinvite=yes
insecure=very

-- features.conf --

[applicationmap]
test => 9,peer,Playback,hello-world ; TEST with sound clip
testVideo => 8,peer,Playback,/tmp/test ; TEST with video clip

-- extensions.conf --

exten => 8160,1,Set(DYNAMIC_FEATURES=test#testVideo)
exten => 8160,n,Dial(SIP/8160)
