SIP Trunking Made Easy
Posted on: January 31, 2018
The phrase "SIP Trunking" or "SIP Trunks", is increasingly common in the world of telecom, but some times it can be hard to determine how it affects your business.
What is SIP?
To understand “SIP Trunk”, you first need understand "SIP". Over the past few years, the telecommunications industry has standardized on SIP as the protocol of choice for phone calls on the data network. SIP, which stands for “Session Initiation Protocol”, is the technology used for establishing a voice communication session on a data network (for example over the Internet). A SIP “session” might be a regular VoIP phone call between two participants, or a multi-party conference call.
What Is SIP Trunking?
Now that you better understand SIP, we can move on to the term “SIP Trunk”. A SIP Trunk provides the same service you get from a traditional analog phone line. The difference is, instead of being a physical wire, a SIP Trunk is a “virtual” phone line which is provided by a SIP trunk provider (Pinnacle Telecom is one of these providers). They use your exiting data circuit of your existing data carrier (T1, Cable Modem, DSL, Ethernet over Copper, High-Speed Fiber, etc) to connect your phone system back to the network.
Why Convert To SIP Trunking?
Because there are no physical lines that need to be maintained with a SIP Trunk, a SIP Trunk is considerably more flexible, feature rich, and resilient than traditional telephone service. Depending upon the types of calls, and quantity of calls you are making, SIP Trunking can save you money, provide the ability to ramp up or down capacity quickly, and get advanced features like DID numbers. Also SIP technology is a big cost savings when transitioning from older technologies like ISDN PRI.
How much is this going to cost me?
SIP trunk pricing varies from provider to provider. Some providers bill for SIP Trunks in a similar manner to how traditional analog lines are billed with a fee per trunk and cost per minute. Other providers charge a flat fee per SIP trunk, with unlimited usage.
