3CX - different sites

[MatthewL]

Following on from the upgrade topic got me thinking about something.

 

If you had 4 organisations each with their own 3CX server and I suppose same could be said with FreePBX, each site independent, in the past on analogue systems I've had you dial a 3 digit code for a site then the extension number can you do this with either of them? There would be a link somewhere but not sure how its termed. We used to call it VPN dialling as we could phone any organisation up and down the UK with the 3 digit code but never had any dealing with config side.

 

Can this be done with modern VoIP systems? Wanting to keep organisations separate but be able to dial each other just wondering like I do.

3CX can do this by setting a bridge up in the SIP Trunks section

Thanks for that, I did see that and did wonder.

 

Is there a correct Telecoms term for this does anyone know?
