Description (partial)

When using mgcp dtmf-relay type nte-gw, a sniffer trace will reveal that digits are sent both in-band (within the audio stream) and out-of-band (dtmf-relay).  Because of this, double digits can be seen in Unity and MeetingPlace.

GW with PRI/CAS backhaul via MGCP to CUCM and mgcp dtmf-relay configured to use nte-gw.
