What is SIP Trunking ?

Channels, trunks, simultaneous call-paths… These are terms that are commonly thrown around when talking about SIP Trunking and always lead to a lot of confusion. The definition of a SIP Trunk is actually quite simple.
SIP or (Session Initiated Protocol) is the telecom industry protocol that defines the signaling and operating standards for initiating interactive end user sessions over a data connection. And a trunk is the circuit between switching systems that actually carries a specific number of calls at a any given time. SIP Trunking offers a business a VoIP connection between their IP PBX and the Telecom carrier’s next generation softswitch, which is capable of carrying one or many concurrent simultaneous calls, that are routed over the customer’s Internet/Broadband connection. Basically, what SIP Trunking offers is a modern day upgrade to older traditional TDM trunks, and offers an improved utilization of current network capacity.

How do SIP Trunks Work?

Traditional business phone systems consist of two key components. The PBX, which provides call management and features such as Auto Attendants and voicemail, and the PRI lines which connect calls to the PSTN (Public Switched Telephone Network) where they are routed to the destination telephone. When SIP trunks are utilized, the IP enabled PBX connects to the data network instead of the PRI lines and the voice traffic travels the Internet to connect to the PSTN. SIP Trunks can also be used with analog adapters or SIP-to-T1 gateways, allowing you to keep your legacy PBX equipment and take advantage of lower telecom costs.

Why do Businesses Choose SIP Phone Service in Tennessee Illinois?
While there are many advantages to the VoIP SIP trunk approach, the primary drivers are cost and flexibility. SIP trunking eliminates the need for PRI lines and the associated cost. Unlike PRI lines, which contain 23 channels, SIP trunks can be purchased in increments as low as one channel, or one concurrent call. This gives businesses the ability to purchase and pay for only what they need and to easily scale as capacity requirements change.

Why you should consider switching to SIP trunking and what to look for in a SIP termination provider. SIP trunking providers offer virtual telephone lines for your PBX and the PSTN. It allows your organization to route calls over your existing high speed broadband connection and bypass expensive ISDN circuits. This reduces your call charges.
