SIP Trunks are Business Phone Lines

Experience enterprise communications with SIP trunking. 

With nexogy SIP Trunking, PSTN connectivity is provided through nexogy’s IP Network. Now your call travels the majority of its path over nexogy’s Network instead of on the PSTN and then drops back down to the destination/facility at the last mile.

By implementing nexogy as the carrier, traditional local and international long distance charges are dramatically decreased as the call travels mostly over the IP network and not on the PSTN.
