Connecting3CXPhoneSystems(Bridges)
Introduction
Youcanconnecttwoseparate3CXPhoneSystemstogether,allowingyoutomakecallsbetween
branchofficesusingyourinternetconnectionforfree.
A“Bridge”canbeassignedaprefix,whichuserswilldialtoaccesstheother3CXPhoneSystem.
Thisprefixmustbefollowedbytheextensionnumbertheywishtoreachontheother3CXPhone
System. For example, if you assign the prefix “5” to a bridge with another office, and within your
officeyouwanttodialsomeonewhohasextensionnumber105intheotheroffice,youwoulddial
5105toreachthatpersondirectly.
Alternatively,youcanassigntheextensionsinoneofficetostartwithonenumber(e.g.1),andthe
extension inthesecondofficetostartwithadifferentnumber(e.g.2and3).Thatway,theusersdo
notneedtodialaprefix,sincethePBXwillroutethecallbasedonthefirstdigitofthenumberthey
arecalling.Inthiscase,theoutboundrule(withprefix1and2),shouldnotremove(Strip)anydigit.
