We’re Passionate About IP Telephony and SIP Trunking
Our founding team has an extensive background in hosting Asterisk and FreeSWITCH PBX systems, both virtual and dedicated, since 2007. We pioneered the concept of the open-source telephony “triple-play,” offering hosted Asterisk, integrated SIP trunking, and pre-configured Polycom and Cisco IP phones. We do it all in an automated, online environment. We have a deep understanding of VoIP call routing and quality of service. We have developed a vast knowledge-base of the hundreds of different router, firewall and network ISP combinations we experienced while hosting thousands of IP-PBX’s. With the launch of SIP.US, our focus is exclusively on SIP trunking and developing the best online control panel in the marketplace.
Our Advantage – Reducing Cost with Automated Provisioning
Everything we build is designed to be fully automated, minimizing the amount of human intervention necessary to operate our business. We find it amazing (and perplexing) that most companies in the telecom industry still rely on manual processes for ordering, provisioning and billing. We can spin up a new SIP trunk in seconds and that’s how it should be. Do you need a new telephone number? Simply query our number inventory by state and area code, pick the ones you want, and buy them. They are ready to use immediately. Need to add a couple of channels to your unlimited SIP trunk? No problem. Do it all online and it’s even automatically pro-rated for you. Need to check your call detail records? It’s easy. We display them in near real-time as soon as you hang up the phone. This automation means lower costs and greater flexibility for our customers.
