Hi,
you could try switching the DTMF mode of the ATA's SIP peer (and also in the
ATA itself) to INBAND transmission.
In this mode, the ATA doesn't need to recognise DTMF tones and your Asterisk
can interpret it.
For this to work, the ATA needs to use a G.711 codec. Inband DTMF needs an
uncompressed codec to work properly.
Another way is (if the ATA supports it) to switch DMTF mode to SIP INFO.
In this mode, DTMF is not interpreted out of the audio stream. For external
peers which are not supporting this mode
Asterisk then generates the proper RTP messages or tones.
With SIP INFO mode I made my best results with all devices, sadly it's not very
common used.
I have tried all of these ideas and it still does that stutter. Can
anyone suggest any other things to try?
