Networking multiple Business Communications Managers
You can also connect multiple offices with Business Communications Manager systems across
your company Intranet. This installation allows for CallPilot to direct calls throughout the system
or for one system to support voice mail for the network. Full toll bypass occurs through the tandem
setup, meaning that any user can call any DN without long distance charges being applied. Users
have full access to system users, applications, PSTN connections, and Unified Messaging. The
network diagram shows two Business Communications Managers, but additional base units can be
added.

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