[Asterisk-Users] Sipura 3000 DMTF

[Vahan Yerkanian]

Try with dtmfmode=auto and DTMF Tx Method: InBand+INFO, this was the 
best configuration for me, although still not 100% guarantee. If the 
dtmf tones are sent very fast without a 1 sec delay, in most of the 
cases asterisk won't detect half of them. There are a couple of patches 
for the trunk regarding this issue, but they didn't work for me.
