Cisco Multiple SIP Trunk to 3CX with different Call Center Agent

[a.aljiledi]

Hello..

I have to ISDN E1 Interface on Cisco Router 2951, each E1 have a different phone number,, and i need to configure a 2 SIP trunk between router and 3CX system,, each phone number connected to a dedicated SIP trunk,, because each SIP trunk will be connected to different Call Center agent,,

I try to configure 2 SIP trunks but all calls were forward to the same trunk, because using the same IP and Port, so any advice to solve this issue?

If I understood correctly:

You want to forward to numbers from the router to the same 3CX system.

In 3CX, you have 2 agents.

If that's correct, then you need to do the config in the 3CX system.

The router doesn't know anything about the agents. So, you could also just use one dial-peer with one pattern-map to forward both numbers to 3CX.

In 3CX, you have to configure, where to route which number (and no, I can't help you on that).

Hi,

You can configure two pots dialpeers matching incoming called-number
(0213660009 and 02136600010). Then you configure cor-lists to ensure that
0213660009 dialpeer can see voip dialpeer 4 and 0213660010 dialpeer can see
voip dial-peer 7.

Here is how to configure cor lists
