Remote Office on 3CX Bridge has wrong Caller ID

[Tularis]

Hello,

We have two offices. One Main office with 3CX and all external calls going to a SIP Provider and one remote with all calls going over a 3CX bridge back to the main office and then out via the SIP provider.

I would to configure 3CX so that all calls made to external numbers from the field office have a different caller ID.
At the moment both sites display the same caller ID.

I have tried changing the settings for the CallerID on the EXTs in the Field office, and I have tried changing the caller ID settings on the Bridge. But nothing is working.

Are you certain that your provider allows outbound caller ID to be changed, to something other than that of the main number? Some regions prohibit this.

You should be able to confirm by changing the Outbound Caller IDlocated under the Other tab, on one of the local extensions.See if that makes a difference. You may have to have a chat with your provider for clarification on this .

We have changed the caller ID via the EXT on the Main Office and this works correctly.
It seems to be something to do with the Bridge.

It looks as if all calls are going through the master pbx, does the slave have a sip trunk registered at his location?

There is no SIP at the Field office.

We own the 404505 number and it is part of the Main Office PBX Sip Provider.

We want all calls to go out via the 3CX Bridge but to have the caller id of 404505 so that ring back will ring the correct office.
Ringing 404505 will ring the Field Office as we have setup a incoming rule to ring the Field office.

Did you change the outbound caller ID for the extensions at the location where the slave pbx resides?

Hello,

Yes, I have changed the Caller ID on the EXT in the Field Office and on the Trunk Connection.
But each time they only show the main line number. We have over 20 DIDs from our SIP provider and it just seems to be the Bridge from the remote office that is not allowing us to change Caller ID
