Branch Offices
Branch Offices provide a powerful tool for interconnecting PBX Systems. Through Branch Offices you can create
a network of systems where dialing phones on remote systems is as easy as dialing local extensions. You can
route calls inbound to a destination on any branched PBX, and outbound through the trunks of other systems
networked in this way. Branch office extensions can even participate in ring groups.

IMPORTANT: Branch Offices communicate using IAX2
protocol over Port 4569. Refer to the Port Forwarding
Configuration Table earlier in this manual for more
information.
