Hi,

We have different model of yealink, T41P/S, T46G/S, and there phone reconized beep like dtmf, so where i go in the voicemail i don't hear the beep and we have dtmf like A or C.
We don't reproduce this problem with other SIP phone like Digium.

I tried change dtmf RFC2833 to SIP-INFO but the problem are always here.

Can you help me ?

Hello !

You could try with the « Inband » type if your VoIP server supports it.
