Multi-location chain with call center
You can create a multi-location chain where one Business Communications Manager runs a Call
Center and passes calls to the appropriate branch offices, each of which use a Business
Communications Manager. A typical use of this would be a 1-800 number that users world-wide
can call, who are then directed to the remote office best able to handle their needs.

To set up this system:
1 Ensure that the existing network can support the additional VoIP traffic.
2 Coordinate a Private dialing plan between the systems.
3 On each Business Communications Manager system:
• Set up outgoing call configuration for the VoIP gateway.
• Set up a remote gateway for other Business Communications Managers.
• Set phones to receive incoming calls through target lines.
• Configure the PSTN fallback and enable QoS on both systems.
4 Reboot each system.
5 Set up a Call Center on the central Business Communications Manager.
