Recently, we are no longer able to dial by extensions between offices. The offices are connected via ipsec tunnel with all ports allowed between the offices. I can dial direct numbers xxx-xxx-xxxx, and it works fine, but when dialing by extensions, it rings, when the person pick up, there is no audio on both sides. I know someone is there because the phone does not disconnect until the person hangs up. I checked the firewall on both ends, and all ports are allowed over the tunnel for both voice and LAN on both sides. I did a list trace and it shows the local and remote phone are connecting. Any ideas? Thank you.
 
You posted in the Partner Edition forum which is not capable of IP phones or SCN... Please post to the IP Office forum you will much more likely get a response there.

The truth is just an excuse for lack of imagination.
