416 Chapter 45 Configuring VoIP trunk gateways

— If your network uses a gatekeeper (H.323 trunks only), there are also specific settings

that must be set on the your system to recognize the gatekeeper, and also within the

gatekeeper application, so that VoIP lines are recognized. Refer to “VoIP

interoperability: Gatekeeper configuration” on page 423. If there is a gatekeeper on

the network, you do not have to configure remote gateway settings.

— If you plan to use H.323 trunking, and you have a firewall set up, ensure that the ports

you intend to use have been allowed.

• SIP network applications consideration:

— If you plan to use SIP trunking, and you have a firewall set up, ensure that the ports

you intend to use have been allowed.

“Using VoIP to tandem systems” on page 367, and “Configuring fallback over a VoIP MCDN

network” in the BCM 4.0 Device Configuration Guide (N0060600).

Configuring VoIP trunk media parameters

The VoIP trunk media parameters allow you to specify the order in which the trunk will select IP

telephony system controls for codecs, jitter buffers, voice activity detection and payload size.

There are two types of routing protocols used for VoIP trunks H323 and SIP. Refer to the

following procedures to configure the settings for these protocols.

To configure H323 media parameters

1 Click Configuration > Resources > Telephony Resources > IP trunks

2 Select the H323 Media Parameters tab in the bottom panel.

3 Enter the information that supports your system. Refer to the information in Table 35. Ensure

that these settings are consistent with the other systems on the network.

4 Set up the local gateway parameters. (“Setting up the local gateway” on page 416)

To configure SIP media parameters

1 Click Configuration > Resources > Telephony Resources > IP trunks

2 Select the SIP Media Parameters tab in the bottom panel.

3 Enter the information that supports your system. Refer to the information in Table 37. Ensure

that these settings are consistent with the other systems on the network.

4 Set up the local gateway parameters. (“Setting up the local gateway” on page 416)

Setting up the local gateway

The call signaling method used by the local gateway defines how the BCM prefers call signaling

information to be directed through VoIP trunks. Call signaling establishes and disconnects a call.

You set this information in the local gateway panels.
