MX-ONE Unable to send DTMF from digital phones

[carmalegno]

Hi,

Is there a way so that my Aastra 4225 can send dtmf through a sip trunk ? I tried capturing the packets, no dtmf is being sent to the sip provider. It works okay if i'm using analog trunk.

MX-One 6.0 SP2 HF6
PARNUM:56 is already 15.

Solved.
After wiresharking, looks like the provider didn't enable the RFC2833.
