Looking to enable Mobile Voice Access/Two-stage dialing on our existing voice gateways. Both are currently MGCP and I'm looking for a migration strategy. Is it possible to have the h323 and MGCP running simultaneously?
Although - for a single PRI you will not be able to send MGCP and H.323 calls out simultaneously. When the PRI is MGCP controlled, only MGCP calls can go out of it. This is different from something like a SIP/H323 scenario where both can send calls out simultaneously.
Yes - if you're using MGCP for PRI and H323 for VXML that's perfectly fine. It's only an issue if both protocols are trying to use the same resource, because MGCP comes in an envelopes the PRI and other processes will not work correctly with it.
just to jump om this one, can you have Mobile access i.e SNR you cna use a MGCP GW if the CUCM is 6.X and above? . When it was on a seperate I understand it was only H323 but now it is part of CUCM I was told MGCO can also work but for the two stage option (DISA) it is still H323 due to the need to have a VXML Script- is this correct
