IP Telephony Configuration Guide
Chapter 5
Typical applications
This section explains several common installation scenarios and provides examples for how to use
VoIP trunks and IP telephony to enhance your network.
M1 to Business Communications Manager over IP trunks
The Business Communications Manager 2.5 can connect with a Meridian 1 to extend an existing
network. In this type of installation, capabilities of the M1 are available to phones on the Business
Communications Manager 2.5. For example, a company that has a M1 in a Head Office may want
to set up a warehouse in another region. The warehouse can then call the head office across VoIP
lines, bypassing long-distance tolls.
