Telephones

The BCM can communicate using digital telephones (7000, 7100, 7100N, T7208, 7208, 7208N,

7316, 7316E, 7316E+KIMs, 7310), cordless telephones (7406), and IP telephones and applications

(Nortel IP Phone 2001, IP Phone 2002, IP Phone 2004, Nortel i2050 Software Phone) 2007/

11XX. With this much flexibility, the BCM can provide the type of service you require to be most

productive in your business.

While analog and digital telephones cannot be connected to the BCM system with an IP

connection, they can make and receive calls to and from other systems through VoIP trunks. Calls

received through the VoIP trunks to system telephones are received through the LAN or WAN

card and are translated within the BCM to voice channels.

Gatekeepers

A gatekeeper tracks IP addresses of specified devices, and provides routing and (optionally)

authorization for making and accepting calls for those devices. A gatekeeper is not required as part

of the network to which your BCM system is attached, but gatekeepers can be useful on networks

with a large number of devices.

When planning your network, be sure to consider all requirements for a data network. Consult

your network administrator for information on network setup and how the BCM fits into the

network.

SIP Proxy

The SIP proxy routes calls that are not defined in the routing table. If the dialed digits do not match

any of the predefined routing strings, the call is sent to the proxy IP address and then the proxy

routes the call.

IP Network

WAN

A Wide Area Network (WAN) is a communications network that covers a wide geographic area,

such as state or country. For BCM, a WAN is any IP network connected to a WAN card on the

BCM system. This may also be a direct connection to another BCM system.

Note: Model 7000 phones are supported in selected markets only.
