4.2 IP Trunks

Voice over IP (VoIP) trunks, are signaling channels that simulate how CO lines

work. However, VoIP trunks transmit data to the IP network over a LAN or IP

network rather than over physical lines. Once the VoIP trunks are set up, you

can assign them to line pools, and program their behavior in the same way you

would PRI lines.

VoIP trunks use line numbers, which appear under

. To access VoIP lines, you need to

enter software keycodes. Each keycode supports a specific number of trunks. No

entries appear in the Enabled VoIP lines field until you complete the IP Trunks

Settings field, which displays when you click IP Trunks under

 IP trunks

VoIP trunks should be configured to use a single line pool. Do not mix other

trunk types on the same line pool (e.g. analog, PRI, etc). The VoIP line pools are

assigned to routes, which, in turn, are configured with destination codes that

route calls to the BVoIP network.

see if trunks have been allocated. You should have a number of IP trunks

displayed. The total number of lines indicated corresponds to the number of IP

trunks licensed by Nortel for your BCM450. See figure below.

Note:

The

BCM450

(

Release 1.0

) offers two VoIP trunk license options: SIP

Gateway Trunk License and VoIP Trunk Gateway License. The SIP Gateway

Trunk License enables SIP-only trunks and the VoIP Trunk Gateway License

enables SIP or H.323 trunks. Either type of trunk licenses can be used for SIP

signaling with AT&T IP Flexible Reach service.

Customers that desire a lower cost or have no requirements for H.323 should

choose the SIP Gateway Trunk License option.
