VG224 with H323 gateway and CUM

Hi

Is it possible to deploy two VG224 with H323 gateway which connect to the CUCM in the head office.

Call flow

When a user dial local number or international number from the analogue and cisco phone the call should be routed to the PSTN line  via the H323 gateway, but when they try to ring other site in the company the call should be routed to the CUCM (four digit dialing). All incoming call form outside the company should come via the PSTN.

 

See Diagram Below

Hi Jamie,

Does the configuration below look okay in what we want to achieve?

Valincia,

first of all you need to make a protocol strategy for this network and i prefer it be like this:-

1- add the 2 VGs works as sccp gateway with the CUCM.

2- add the 2 IP-phones as sccp client with the CUCM.

3- add the 2961 router GW as MGCP with the CUCM. ( you didn't mention CUCM version so be aware of the router if its supported as MGCP router inside the CUCM )

after doing that you could do what you need from call routing inside call manager.

We are using CUCM 8.6. We would prefer to add the 2961 as a h323. Because most of our sites use H323.
