Configuring VoIP trunk gateways

The following explains how to configure voice over IP (VoIP) trunks on a BCM system for
incoming traffic. A VoIP trunk allows you to establish communications between a BCM and a
remote system across an IP network.
The following path indicates where to where to configure VoIP trunks in Element Manager:
• Element Manager: Configuration > Resources > Telephony Resources > IP Trunks
Task: Set up VoIP gateway parameters
• Set up the media parameters for the gateway.

• Set up the local gateway parameters, including H323 gatekeeper or SIP Proxy
settings, if necessary.
• Set up the routing table, if one is required.
page
• Configure the line parameters.
Prerequisites
Ensure that you have obtained the following information or familiarize yourself with the
requirements before continuing with VoIP trunk configuration:
• Keycodes: Obtain and install the necessary keycodes for the number of VoIP trunks you want
to support on the system. See the Keycode Installation Guide (NN40010-301) for more
information about installing the keycodes. Talk to your BCM sales agent if you need to
purchase VoIP keycodes.
Each keycode adds a specific number of VoIP trunks. You must reboot your BCM after you
enter VoIP keycodes to activate trunking.
The FEPS service will restart automatically after you enter the VoIP keycodes.
If you want to use the MCDN features on the VoIP trunks, you will need an MCDN keycode.
If you have already deployed MCDN for your SL-1 PRI lines, you do not require an additional
keycode.
• Media gateway parameters: Ensure that the gateway parameters are set correctly for the IP
trunks.
• H.323 network applications considerations:
