SIP VoIP (Trunk)

Connect your on-premise PBX to our IP network for more flexibility and cost-savings

Did you know that 50% more businesses use Internet telephony than traditional Time-Division Multiplexing (TDM)? Our SIP VoIP helps businesses start the transition quickly and easily by using their existing on-premise PBX to connect with our Internet Protocol (IP) networks, delivering immediate flexibility and cost savings.

Why is SIP Trunking Better than TDM?

Lower Cost, Higher Sound Quality

Lower Cost, Higher Sound Quality

Time Division Multiplexing (TDM) is traditional business telephony that uses low-bandwidth copper channels for communications that are managed by monopoly players, like AT&T, Verizon, and Comcast. Your cable or fiber data bandwidth is over 100 times more robust, which means you pay a fraction of the cost. This, combined with using a competitive telecom provider, like Convergence Cloud, explains why SIP Trunks save our customers up to 50% on line rentals and 25% on calls.

Convergence Solutions was incredibly helpful to me when I joined my firm. Convergence had long managed our Telecomm PBX and handset equipment so I turned to them to help our full office renovations. Once our immediate phone relocation and wiring needs were handled promptly and professionally by the Convergence team, I found we were using a variety of unrelated vendors to manage our voice, conference call, IP Phones, and internet services. It was clear there was a lot to improve upon in terms of service, price and quality with this confederacy of dunces, so I stopped to talk with Steve Solton about our overall communications infrastructure.  After a brief discussion, it was apparent Convergence were experts on more than just the PBX in my back room, they began to identify our network server and port issues, suggested solid state industry enhancements, AV Conferencing solutions and  much more.  We are implementing many of these ‘Convergence’ solutions presently, none of which are minor, but all which are being expertly handled.
