Solved Change outbound Caller ID of SIP Trunk

[siscom]

Good Afternoon Colleagues
I hope you are doing well . I have SIP trunk between 3CX and third party IP PBX . The main trunk number at 3CX is 20000 . I have internal extensions at 3CX from 100-199.

When calling the third party IP PBX , What is displayed as caller ID at the IP Phones connected to the third party IP PBX is 20000.

How can i override this by the extension number (100-199) of the calling user at 3CX ?

Best Regards

Use a bridge instead. SIP trunks on 3CX will never do what you need the perfect way (we tried many times.)

Hello Frederick
Thx for your message . I used Master Bridge at 3CX side . The trunk is up from both side . When calling from 3CX (any extension from 100-199) , What appears as caller ID at the IP Phones connected to the third party IP PBX is 20000 (which is main trunk number) so how to override this by the extension number (100-199) of the calling user at 3CX ?

Best Regards

Play with the inbound/outbound parameters in the bridge config.

Good Morning Frederick
Thx for your support . Master bridge has no Inbound parameters at all and only one outbound parameter which is "From : Display Name"

But anyway , I manage to do what is required from the third party IP PBX.

Best Regards
