I have two sites running CME4.2 over a checkpoint VPN tunnel. When i call from either site, the phone rings but no audion at all.

Firewall administrator says all ports are open between the voice network on both sites.

Any ideas?

Is the CMEs in the voice networks as well? same as the phones. CME tends to terminate the voice stream coming from the phones and going to an external system.

Get him to look at the logs on the checkpoint and tell you if there is anything to learn from that.

HTH, Avner.
