[cisco-voip] CallManager > Device > Trunk (SIP)

[Jason Aarons (US)]

My router has a PRI with SIP dial peers back to CallManager (Trunk), which is integrated with Unity Unified Messaging 8.0(3) (with Exchange).

The handsets are new 7962s with SIP 9.0(3) load.

What dtmf-relay method should my router's dial peers use so that DTMF works with my Call Handlers, etc and the phones have no DTMF issues?

What I'm really asking is can Unity Unified (with Exchange) 8.0(3) handle rtp-nte (RFC2833)?
