Companies with multiple offices in different geographic locations may need the ability to communicate between offices in a cost effective way, traditionally calls over the PSTN and GSM networks could easily ramp up heavy monthly bills.
Using the trunk to trunk application on the pbxnsip IP PBX Phone System this is now not the case, internal calls can be routed over a SIP trunk and the IP PBX will use the internet connectivity to transfer the calls free of charge.
