MGCP Gateways and Cisco Fax

Question

We are considering adding a fax solution to our IPT infrastructure using Cisco Fax (Captaris RightFax). Ideally we would like the same voice gateways to terminate the fax calls (internal voice calls use QSIG and external calls use Q.931). Can this be achieved with MGCP-controlled Voice gateways? Can T.38 fax be configured with an MGCP gateway. I have seen examples where H.323 dial-peers are required to talk SIP to the Fax Server.
If not, is an alternative to use a back-to-back PRI connection between a voice gateway port and the Fax Server ISDN card, with appropriate route patterns in CallManager to route the fax calls to Fax Server, using Cisco Fax Relay?

Answer 1

with cm 4.2.3 there is mgcp t.38 support implemented.
