I'm new to the Callmanager world and have CUCM 8.6 setup in my lab. I have several Cisco 3905 SIP phones registered with the callmanager and would like to perform some experiments with H.323. I've downloaded SJPHONE H.323 client but can't seem to get it completely working. My setup includes the callmanager, 2 Cisco 3905 sip phones, 1 sjphone H.323 softphone client phone all plugged into a gigabit switch. Here is what I've done so far:
1) registered sip phones
2) registered SJPHONE as H.323 client
- SJPHONE has the callmanager IP setup as the gateway.
3) registered UIP300 as H.323 client
- callmanager IP is entered in the UIP300 as gateway
With this setup, SIP to H.323 calls are successful. However, H.323 to SIP fails after the SIP phone rings briefly.
What am I doing wrong? Is just the CUCM adequate or do I need a gateway or a gatekeeper or anything else to make this work? Any help would be greatly appreciated. Thanks a ton!!
