VoIP networking
When you choose voice over IP (VoIP) trunks to make network connections, the process is very
much the same as using land lines, except that you must also create a Remote Gateway record
which identifies the IP address for the target system. Note: If the IP system has a Gatekeeper, the
Remote Gateway record is not required. You need to supply the IP parameters of your system to
the Gatekeeper administrator instead.
You also need a VoIP keycode before you can activate VoIP trunks.
MCDN networking over VoIP, which is always between a Meridian 1 and one or more Business
Communications Managers, is set up and works the same way as it does over PRI lines. You still
require the MCDN and IP telephony software keys and compatible dialing plans on all networked
systems. Refer to
“Understanding MCDN network features” on page 532 .
The major difference between a PRI MCDN line and a VoIP MCDN connection is that the VoIP
trunk requires Local and Remote Gateway settings. Under
Services , IP Telephony , H.323
Trunks , Remote Gateway , ensure that Gateway Protocol is set to CSE if you want MCDN
functionality for the VoIP connection to the Meridian system (BCM 3.5 and newer software). The
Gateway Type would be set to IPT (M1 IP Telephony), as it would for any non-MCDN VoIP
connection to a Meridian system. You can also use MCDN VoIP to other Business
Communications Managers. There is a Gateway Type for each version of Business
Communications Manager software that supports this function.
For details about setting up gateways and configuring VoIP trunks, refer to the
IP Telephony Configuration Guide.
