I have a site that is using an H323 GW that is configured to use a CUCM 6.0/Unity 4.0 cluster. There is a 1MB line on the gateway for incoming calls which forwards to an AA on the Unity server. Normal inbound and outbound calls work fine. However, if a user forwards their Cisco IP phone to their cell phone it fails:
The auto attendant tells you âwait while I transfer your callâ and then you hear 3 beeps. The user's cell rings once and then the call disconnects on the user's phone. The call stays connected on the caller's phone.
This is a new setup with h323 so it probably something simple.
