[Asterisk-biz] DTMF issues with MCI SIP termination.

[Sergey Kuznetsov]

Hi there,

Does anyone had an issue with DTMF codes passing via MCI SIP trunks?

For me it doesn't work at all. I analyzed RTP traffic and it doesn't
show any presence
of RTP payload 101 even if peers negotiated about this via SIP messages.
And I don't hear any
DTMF codes sounds when I pass it thru MCI.


Respectfully,

Sergey.
