Setting Up Remote Gateways; Configuring A Remote Gateway (H.323 Trunks); Configuring Voip Lines - Nortel BCM50 Configuration Manual

Setting up remote gateways

The following explains how to set up your system to place calls through VoIP trunks. The system
at the other end of the call must be set up to receive VoIP calls. For information about this, refer to
"Configuring a remote gateway (H.323 trunks)" on page
Configuration note: If the VoIP network has a gatekeeper, you do not need to configure remote
gateways, as they are not used.

Configuring a remote gateway (H.323 trunks)

The following explains how to configure the BCM to communicate with other BCMs and/or other
VoIP gateways such as Meridian IPT using H.323 trunks. The remote gateway list must contain an
entry for every remote system to which you want to make VoIP call.
Gatekeeper note: If your system is controlled by a gatekeeper, you do not need to establish these
gateways. Refer to
The following path indicates where to access the remote gateway in Element Manager:
• Element Manager: Configuration > Resources > Telephony Resources
1 On the Modules panel, in the Module type column, select IP Trunks.
2
In the bottom panel, select the Routing Table.
3 Click Add.
The Add Remote Gateway dialog box appears.
4
Enter a Name and Destination Digits for the remote gateway.
5 Enter the appropriate information for the remote system:
• Destination IP: Indicate the IP address of the device you want to connect with. This code
will be part of your destination code programming.
• GW Type: Choose the variable that identifies the type of system or application being
connected to.
• GW Protocol: Choose the protocol that supplies the required call features. None (default)
supplies no feature. This setting is dictated by the type of remote system.
• VoIP Protocol: Select signalling to endpoint - SIP or H.323.
• QoS Monitor: Enable this feature if you are using fallback to PSTN lines and the network
supports QoS monitoring.
• Tx Threshold: Indicate the level of transmission at which the signal must be maintained. If
the signal falls below this level the call falls back to PSTN.
6 Click OK.

Configuring VoIP lines

VoIP lines require a keycode to activate. You also need to set gateway parameters and system IP
parameters to enable the trunks.
