What are the Benefits of SIP Trunking over Traditional PRI?


Twenty years ago the term “Internet Provider or ISP” was foreign to most.  Then AOL made their name known to many; other ISP’s started popping up here, there and yonder and before you know it- every home has the Internet, thanks to Internet Service Providers.  Today’s SIP Trunking is basically the newest business technology phenomenon presenting itself to the world, providing business with data, video, and audio communication over one line.  And those that provide this service to business are known as Internet Telephony Service Providers or ITSPs. 

Why is SIP Trunking so much better than traditional PRI?  It’s simply a matter of technology and cost.  Traditional PRI or Primary Rate Interface is often expensive to businesses; when one business or another makes the decision to switch from PRI to SIP Trunking- they not only save money; they see a much better quality product and service.  More and more ITSP’s are providing SIP Trunking to businesses allowing them to communicate for less money and less need for equipment changes.  You can basically take your current phone system and add SIP Trunking and a PBX switch- allow a qualified ITSP to hook your business up and you’re good to go.

SIP Trunking is more advanced than traditional PRI in that it offers the user more features.  IM- call screening is available.  Unlike traditional conferencing where there were delays and it was more like watching a bad movie; this new IM-Call screening technology makes both users feel like they are actually “there” in real-time.  It eliminates the machine/computerized conferencing that many businesses currently despise.  It streamlines the call and video so without physically leaving one city; you can see, hear, and talk to one another like you are actually in the same room.  Another feature that stands out in regards to IP telephony service; SIP Trunking also allows third party interfacing; something traditional primary rate interface does not.  As technology continues to advance, this feature will, as well.  But even today- some ITSP’s give their clients the ability to voip with multiple businesses and organizations.

Although SIP Trunking is a new concept in the world of communication technology, more and more businesses are opting to use ITSP’s for their business communication needs.   IP Telephony providers allow businesses to grow; seeing long-term savings when looking at the big picture.  In essence, you’re taking all the communication mediums available to a business and combining them into one smooth and exciting network.  Those that utilize SIP Trunking now see big savings and find that the technology is improving each and every day.  And just as time never stands still- neither will the technology of business communication; luckily SIP trunking can evolve with new technology into a well-rounded means for communication for business.
