[Asterisk-Users] zaphfc: All DTMF tones are doubled

[Tobias Jönsson]

When I use signalling=bri_net_ptmp, immediate=no I can dial an extension,
but after connect every dtmf is detected twice. With immediate=yes the
dtmf are detected twice even when dialling the extension number. Could
this be because the telephone adapter both sends INFORMATION and the
inband dtmf could be heard by the zaptel engine?
