SIP Trunking

What is SIP Trunking?

A Session Internet Protocol (SIP) trunk is the new generation of call delivery to your PBX. A SIP permits your business PBX to utilize an internet connection for access Direct Inward Dial (DID) or Direct Outward Dial (DOD) services. SIP trunks are delivered by many traditional telcos and are also offered by an Internet Telephony Service Provider (ITSP). 

Usually, SIP trunks are connected to IP-PBXs, and thus allow a customer to communicate over IP both inside and outside of the business.  This link through the ITSP is their connection to the outside world or the Public Switched Telephone Network (PSTN).   SIP trunks are far more efficient than traditional transports like CO trunks, Channelized T-1s or ISDN PRIs, because they do not require the catacomb of physical wires that were once necessary to delivers these services.  SIP trunks are simply accessed through the internet connection that your company uses to access the World Wide Web.

How can it help my business?

Most businesses are attracted to the price of SIP trunking.  On average, SIP trunks are 50% less than similar ISDN pricing, and less than 20% of the price of equivalent analog services.  So SIP Trunks make an immediate impact on the bottom line. 

SIP Trunking also offers amazing disaster recovery possibilities.  Because SIP Trunks are not limited to an installed circuit, they can be activated on ANY internet connection.  For instance, if your facility was affected by a wide spread power outage, your IP PBX could be moved to another location that had power and internet and, immediately, the system would be functional, with the same phone numbers that were present at the blackout site by using a SIP phone.

Finally, SIP Trunking allows for an easy way to create "virtual presences" from a marketing perspective.  Our carriers offer telephone numbers from different cities and states, which can all be provisioned through the same SIP trunking interface.  Setting up shop in a new state is as easy as a few clicks and suddenly your are placing and receiving calls from 5 states away, with no premium call forwarding charges or additional usage charges.
