Using VoIP to tandem systems

You can connect multiple offices with BCMs across your company intranet. With this installation
CallPilot directs 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, PSTN
connections.
Figure 102 demonstrates a multiple-BCM50 network. The network diagram shows two BCMs, but
additional base units can be added.
