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.
