I have UCCM version 7.0, IP communicator version 7.0.2 and Check Point firewall for VPN. My IP communicator works fine when I'm in LAN.
When I connect through VPN, IP communicator is registered with UCCM. The IP address of IP communicator is the IP address of PC from VPN pool. But, when I call some IP phone in LAN (the phone is in the same LAN as UCCM), the phone ringing and when the phone goes off-hook, my communicator lose connection with UCCM and resets.
On CP firewall I got an error:
Illegal redirection 10.10.16.10->10.10.17.66.
10.10.16.10 is the UCCM server and 10.10.17.66 is the IP phone in the same VLAN.
What can be a problem?
