2 Site Connection

[KhaledQuenawy]

i have 2 branches for my company every site have its own separate outside phone line (analog.. like pstn ) to communicate with others ... i want to deploy 3CX phone system what should i do to :
1- make free calls between 2 sites
2- every site can make outside call with its analog lines ... and can use other site outside lines if its available
3- if one site Down ( internet of line any thing ) the other site can make outside call with its own analog line
how to do this ??
i install 3CX server in one site and SBC in the other site >>or i have to install 2 3CX server and connect them Bridge ???

Couple of options.

1. Two 3cx installations and bridge them together

2. porting the pstn lines to sip lines. Setup one 3cx.server and have all sip trunks connected to this installation and install sbc at the other location

3. As above, install sbc in the cloud with sip trunks and use sbc at the remote sites

Some of the options may change, how many extensions at each location.

the 2 licence should be similar

If this requirement is important, then the only way it is achevable is to install two 3CX servers, one at each location, and bring the "local" line into the respective PBX using SIP, or through a gateway. Using a PSTN gateway would ensure that even if the internet went down (if that is a regular occurrence, and a concern), a site could continue to function. Both sites can be bridged allowing outbound calls from either site through either site
