Locations with H323 and IPIPGW

Unanswered Question

I working on implementing SIP trunking using an IPIPGW and have discovered during testing that the Call Manager Locations construct is not working to provide Call Admission Control.

topology is:

CCM 4.1.3 ----H323------IPIPGW-------SIP------Carrier

All outbound calls are pointed to the Carrier. I thought that since the phones are communicating with Call Manager and the Call Manager knows that inbound and outbound calls are using the associated IP-IP Gateway that this should work. Does this require a Gatekeeper?

As always any advice would be appreciated.

Xcoder on IPIPGW with g729 on H.323 leg are supported and g726/g723 on SIP is not currently supported on IPIPGW.

First locations on CCM work different than want you Gold CAR or QoS setup.

Locations looks at the call as 24k when you add the overhead onto the packets for the WAN the call is 32k if using 729.

so 96 is = to 4 calls in location but on the WAN it is 128K.

Also you have to use MTP's with H323 to SIP IPIPGW

I have it working with the Verizon solution on 15 Pilot sites.
