After some modifications it seems to move in the desired direction.
In shtoom/app/doug.py - incomingRTP I changed
- if packet.header.pt is PT_NTE:
+ if packet.header.ct is PT_NTE:
and I added to shtoom/doug/voiceapp.py quite
some things from shtoom/doug/leg.py regarding
the DTMF processing.
Now the ConferencingApp's announceFile aborts if
a DTMF event occurs.
My changes are more based on guesses than on knowledge ;-)
especially I'm uncertain if they follow Anthonys intentions,
therefore any advice would be appreciated!
Regards,
Frank
