[cisco-voip] Does Unity Connection 7.1.2a support SIP RFC 2833 for DTMF

[Adam Frankel]

Jason,

 

I believe it does (don't quote me on that) but one way to tell would be to
check the CCM traces for the Capabilities Response sent by the Unity port
when it registers with CUCM.  Check for 257.

DTMF

 

I have a SIP Trunk from Verizon Business running thru ACME Packet box to
CallManager 7.1(2a) which then routes to users voicemail on Unity Connection
7.1.2a connected via SIP trunk.

 

If I press Zero or another dtmf key press does Unity support RFC2833 for
DTMF or is a dynamic MPT resource needing to be invoked ?
