G722 and DTMF issue


Recommended Posts



I have tried to use HD telephony codec (G722), quality is better however it seems that DTMF are not working.


Phone : SPA525G

PBX Vodia latest version


For instance, when I try to call my voicemail, i enter my PIN but nothing happens.


Thanks for help,

Ok I solved the problem.


On SPA525G:


In Extension settings, if you plan to use G722 (Advanced setting), please be sure that :


DTMF Process AVT: is set to YES and :

DTMF Tx Method: is set to AVT


and that you use G722 as preferred codec !
