This optional ipbx module is installed under Advanced Setup → Modules. Registered modules are displayed with registered module.

Manage multiple sites from a single master server and simplify communications across all ipbx servers. ipbx's multi site support let's you add cost saving interconnects (trunks) with very little effort.

Multi Site support allows you to configure a dialplan master server and up to 200 slaves that synchronize dialplan information. This system is independent from other services and provides failover capabilities between operating sites even if the master system is down.

Configuring Multi Site

It is recommended to carefully plan your diaplan to avoid overlapping digit patterns across your locations.

To access the multi site configuration click on 'Advanced Setup → Multi Site. On the master server select Currently operating as Master (default setting). The master IP address is taken from the Advanced Setup → Configuration → ipbx IP Address. This is the IP address used by the slaves to synchronize dialplan information.

Take note that your configuration needs to be able to accept unauthenticated calls. If you plan to use IAX make sure you have an IAX guest entry on each system:

 [guest]
 type = user
 host = dynamic
 context = incoming

Adding Peers

Click on add slave peer and enter the remote ip Address as well as descriptive name and extension pattern. Patterns always start with a '_' underscore. In the peer configuration make sure you have your peer set to operate as slave and configured to use the master's IP address. Select the type of connection, either SIP or IAX2.

Special Characters for Pattern Matching

  X          matches any digit from 0-9
  Z          matches any digit from 1-9
  N          matches any digit from 2-9
  [1237-9]   matches any digit or letter in the brackets
             (in this example, 1,2,3,7,8,9)
  .          wildcard, matches one or more characters

Examples

  _NXXXXXX        matches a NANP 7 digit telephone number such as 555-1212
  _1NXXNXXXXXX    matches an area code and phone number preceeded by a one such as 1-860-555-1212
  _9011.          matches any string of at least five characters that starts with 9011,
                  but it does not match the four-character string 9011 itself.

Master Failure

If for some reason the master becomes unreachable, slaves default to cached information and revert back to live information as soon as it becomes available again.
