What is SIP?

 SIP or Session Initiation Protocol is most widely used to initiate and terminate Voice Over Internet Protocol (VoIP) calls.  A SIP trunk is a VoIP connection that uses SIP to connect telephony equipment (e.g. PBXes) to the publicly switched telephone network (PSTN).  In other words, SIP Trunks are a “new  type of phone line”  that ride over a broadband data connection.

Why should I use SIP Trunks?

Voice over IP and SIP has evolved over the course of the last 10 years to the point that SIP trunks have become a viable substitute for traditional business voice services.  In fact, the vast majority of Fortune 1000 companies have been using this technology for nearly 10 years.  Millions of smaller businesses have also transitioned to SIP in the last 2-3 years. 

Why are companies like yours changing to SIP Trunks?  Some of the benefits and features of SIP trunks are as follows:

How do I get started with SIP?

We first need to determine if SIP trunks are available in your area. We partner with Clearfly Communications, go to https://www.clearfly.net/availability/  to see if your area is served.  Since SIP trunks utilize your existing broadband connection (cable, DSL or T1), the quality and reliability of service are dependent on your broadband connection.  Not all broadband connections are the same.  To see if your connection will qualify for service use an easy-to-use tool at http://speedtest.clearfly.net to assess whether or not your broadband connection meets the quality requirements for SIP.
