MGCP, H.323 and SIP on the same gateway
It is possible to have MGCP and H.323/SIP running on the same gateway at the same time, with some calls using MGCP and other calls using H.323 or SIP. MGCP is enabled per voice-port. Once configured, that port must always be under the control of MGCP. If there was a separate port without MGCP enabled, that port would route the calls using normal dial-peers with h323 or SIP. Calls that do not go through an MGCP-controlled voice-port can be treated as regular incoming CVP calls.
