Routing calls between 2 trunks configured in 3CX

[jawadaliqamar]

I have 2 Generic SIP trunks configured in 3CX.

1. First SIP trunk is with CUCM IP (Simulated PSTN).
2. Second SIP Trunk is with a third-party PBX.
3. Both CUCM and third-party PBX have SIP Trunks configured to 3CX.

I want to achieve the following with 3CX.

a. When the call is dialed to first CUCM SIP trunk, Main trunk number, it should route to the Second SIP trunk.
b. When the call is dialed from the Second SIP trunk, it should go out using the first SIP trunk (CUCM IP).

How can I achieve this?

No it's not supported. You should use a different switch software like Freeswitch or Asterisk and code the whole thing yourself.

3CX is not meant to be used like this.
