Keep your existing PBX but enjoy all the cost savings and flexibility of VoIP.
GlobalPhone provides SIP trunking on most PBX equipment, including the manufacturers shown below. Some of these systems have native support for SIP trunking, in which case no additional hardware is required. For PBX systems without SIP support, GlobalPhone can provide a VOIP gateway to convert from SIP VOIP signaling to traditional POTS or T-1 trunks. These gateways vary in size from two port plain old telephone lines (POTs) lines to Quad T-1 PRI systems. For additional descriptions, please visit our Gateways.
