What is the Difference Between SIP Trunking and VoIP?

Confused about just what is the difference between SIP trunking and VoIP? How are they related and what are the differences? In simplest laymen’s terms we will provide the practical answer.

VOIP “voice over IP” is a generic term used to cover all voice traffic over the internet protocol.

SIP trunking is simply voice over IP, using the SIP signaling protocol, but instead of using a single SIP user the service provider is providing many. Basically like a T1 circuit, but using voip with multiple trunks.

The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. It can be used to create two-party, multiparty, or multicast sessions that include Internet telephone calls, multimedia distribution, and multimedia conferences.

Voice over Internet Protocol, also called VoIP, IP Telephony, Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband is the routing of voice conversations over the Internet or through any other IP-based network.

SIP in some cases is a Type of VoIP. …

Since SIP is Session Initiation Protocol, and is a form of VOIP, it is used as a digital voice emulator/PRI replacement. It gives VOIP service more capabilities, such as DID’s (Direct Inward Dial numbers).  The benefit of this service on the commercial level is the ability to avoid buying a PRI card to accommodate a PRI. SIP trunks usually require SIP licenses and connect right to the system. SIP  trunks  are typically more cost effective than copper or t-1 circuits. At Comtex, we have clients who have upgraded to SIP trunks and the savings from the SIP trunks, paid for a new Samsung system in the first year of use.

SIP trunks are essentially have the power of PRI without the cost or limitations. SIP is only limited by your bandwidth, and carriers are coming up with some pretty interesting options.

This will be an area that many will need to become more familiar with, especially in the call center world.

Technology Makes Off Site Working Easier

Did you read the Bergen Record on October 10, 2010? There is a great article, Technology making off-site working easier” by Carol Lawrence. The article highlights that technology is offering mobility features to small businesses by allowing it them to keep “valuable employees, widen sales territories, lessen employees’ commuting stress and even hire overseas.” The article also states that “nationally, the number of telecommuters grew to 17.2 million on 2008 from 12.4 million in 2006. 

Today’s workplace is no longer defined by the building with your company logo on it. Home-based employees and road warriors are becoming commonplace these days, and your communications system has to operate where your employees are most comfortable, everywhere.

Mitel and Samsung IP telephone systems allow you to easily accommodate home, or road based employees by seamlessly connecting incoming calls to your remote location. Off site IP phones allow your transient workers to handle, hold, conference, transfer or page just as if they were in the office.

A Samsung or Mitel system can offer you the following remote worker features:

  1.  Get your voice mail messages sent to your email in your cell phone or PC at home.
  2. Give out 1 number or extension to your clients that will simultaneously ring at your desk, cell and home phone. 
  3. Use an IP phone at home, your cell phone or a softphone in your computer and be directly connected to the office; eliminate toll calls to the office. 
  4. Make your cell or home phone a virtual extension of the phone system at the office. The phone functions as if you were in the office. Seamlessly transfer calls back and forth, put a call on hold at the office or on your remote phone, page over head at the office and check your voice mail.
  5. With SIP trunks, you can have a local presence for your remote workers, anywhere in the state or country by using their local telephone number that rings into your office.

Comtex can provide you with the technology to offer teleworking at your business.
