[Asterisk-Users] Sending digits from SIP to Asterisk's VoiceMailMain

[Innocent Evil]

my sip phone have dtmf relay: rfc2833
asterisk sip.conf have dtmf relay: rfc2833 in associated context.

I tried with Inband.. but g729 doesn't support it. I have g729 liscence from
digium
I havn't try with INFO yet.

I prefer to have rfc2833 as dtmf relay.

Is there any other thing that can cause this issue?

Thanks,
