SIP Trunk and Prefix

[ahqswitchroom4466]

Hello sir
Now our org want to shift from E-1 to SIP Trunk. We have 600 SIP Trunk license. I create 48 SIP trunk for different PABX. But i can create only 8 Prefix using ARS. How can i create other 40 prefix for sip trunk.
Thanks advance

Ok let's understand the topology ,sip is owned (SIP-ABCF) or provided by ITSP (SIP-ISDN)?.

Do what haroun said - use network/routing prefixes.

But network/routing not work with sip trunk.

You mean you configured it and it didnt work?

Check System documentation, volume IP-PCX networks, chapter 6, figure 6.65 and paragraph 6.3.5.
First line goes like this:

A SIP external gateway allows a group of sets or external network to be reached via SIP. Access to an
external gateway may be via a routing number or via ARS.

Check this part - 6.3.5. It has very good example of configuring networking with SIP.

Create the Remote Trk group meaning the SIP Trunk Group with the correct Node number in your PCX, New ARS with that Trk Group and away you go
