Asterisk does not catch all DTMF tones


When i call my Asterisk box thru my provider, once in a while the DTMF digits get lost, Asterisk does not catch them all.
Should i include something like this on the trunk configuration?
dtmfmode = rfc2833

This is what i have on al my extensions.


In many cases rfc2833 is what is used. It is the default dtmfmode in Asterisk so specifing it, it shouldn’t make a difference. It could be packet lose between you and your provider.
