Multiple 3CX installations interconnecting

[KCL]

Hi everyone. First post here.

Is it possible to have a 3CX servers installed on several sites globally and have them linked in some way? We have clients who would like to configure a local 3CX server on each site and then have them link together so that the internal extensions are aware of each other. Since their locations are on separate continents (Moscow, Dubai, London, Africa) the idea of having a centralized 3CX doesn't appeal due to latency and the need to have a local number/DDIs for each office. Can the separate 3CX installs be configured to allow transfers of calls / internal calls between the sites to internal extensions?

Thanks

Hi

Use the 3CX Bridge.

We have a few offices connected using this bridge method. And it works pretty well.
For each extension outbound ID, we put the way for other offices to reach them. So, extension 15 at location 155 is 15515.

Ie: My main office is a 4 digit system. The remote offices dial 4 digits to reach corporate.
The field offices are 2 or 3 digits. You must dial the location code first, followed by the extension.
The prefix is required so the phone system knows what system to contact. This is all done via Outbound Rules.
