Using 1 SIP number from 2 different locations 3CX Server

[ozal.e]

Hi,
In our office in point A, calls to landline numbers on the 3CX server work normally. There is also a separate 3CX server in point B. I want that when calling a landline number from the 3CX server in point B, calls should go out from the SIP number in point A. There is no SIP and GSM number in point B. All settings have been made. However, only mobile GSM forwarding works. When calling a landline number, for example, 3XXXXXX, the line is disconnected. In our landline numbers, there are 7 digits. If I write the city code (012) in front of the number, the call will go through. But the call will go through mobile GSM. I need it to go through the SIP number. On point A, that is, the main server, everything works correctly. I should also note that the version of the server in point A is Version 20.0 Update 7 (Build 943 Beta), and in point B is Version 20.0 Update 7 (Build 979 Beta). Cal Log: Dialed: (4XXXXXX) → Via rule: To landline (4XXXXXX) → Via trunk: 3XXXXXX (4XXXXXX) → Server error

If Point A and Point B each have their own 3CX system and are connected via a bridge and appropriate outbound rules, then you can also set it up so that all calls from Point B are routed via Point A's telephony connection.

Some notes:

1. Currently, all 3CX v20u7 systems are not yet intended for production use.
2. If 3CX systems are connected via a bridge and tunnel, it makes sense for all participating systems to use the same 3CX version.
3. If point B doesn't have its own SIP lines (never has and never will), then your idea may be more of a 3CX SBC scenario than a 3CX PBX there.

For simple call routing, over a bridge trunk, the 3CX version of each PBX should not make a difference. You might, however, have issues with Presence.

...and using an SBC, in this scenario, make a lot of sense, unless you have some other trunking located at "Point B", that can't be moved to A.
