Peer SIP Trunk Unreachable


We have 2 PBX ( 6204 and 6208), I have created Peer SIP Trunk in both PBX but it is showing unreachable in both PBX.

Actually, both are accessible via local IP and Ping is successful


Did you enable the heartbeat in the trunk settings on both sides?


peer via VPN or the Internet?


Yes, its enabled. But it is red light (unreachable )


Local Network


See if the IP of the systems are in the blacklists of each other. I assume that they are remote from one another and if not on a VPN, that port forwarding has been implemented.
