2811 with 2 VWCI-2MFT-T1 combo MGCP and H323

[Jason Aarons]

I have 4 PRIs, I want 3 to be controlled via MGCP, the 4th to be controlled via H323.

Callmanager needs MGCP for Calling Party Name/Number, while Xmedius Fax needs H323 for T.38..can I do this all on one 2800ISR?

Yes you can.

MGCP has to be globally enabled and specified with callmanager ip address and all that (and if you prefer CCM to push config, you may do the ccm-manager config commands as well).

For each T1 controller (PRI) there will be a D-channel (s1/x:23) associated with it.

x = 0,1,2,3 say.

0,1,2 are for MGCP and 3 is for the T1 PRI using H323.

session target ipv4:

Dial-peers 1,2,3 will take care of MGCP, while 3 and 4 will be for H323.

MGCP and H323 should work like "Ships=in=the=night" concept.

Since you are using Fax relay you can enable t38 fax relay under the dial-peer 4 as follows,

fax protocol t38

You can optionally input fax rate and other optional parameters.
