So what is a “SIP TRUNK?” In telecommunications SIP is a “standard” similar to how all electrical plugs in your home are 120V, SIP is what the telecommunications world uses to transfer voice traffic! At Improcom, we also use SIP to provide the fantastic service our customers are used to. As the protocol of choice for phone calls across the market, SIP is a household name to anyone working in telecom! SIP, stands for “Session Initiation Protocol.” When you use a SIP “session” you are really just on a call with another party. Your phone opens a session when you pickup the handset. Normally SIP “session” can range from a regular phone call between two people or even multiple-parties.

​Now that you understand what SIP is a ‘SIP Trunk’ is easy! It’s literally the “trunk” or “pipe” that the SIP traffic can flow through.

SIP Trunk’s are great but you must manage your existing phone system, licensing, repairs and security. After all, a SIP Trunk is just the “pipe” information flows through – it still has to connect to something.

Here is a great quick questionnaire to see if SIP Trunking is a good choice for your business:

  1. Does your business have an Ethernet compatible phone system?
  2. Do you have an in-house technical department that can manage the system?
  3. Do you want to keep your existing phone system?

If you answered YES to all 3 questions – then SIP Trunks may be right for your business.​


  • You no longer need expensive bundles of “PRI” or Primary Rate Interface which runs over outdated copper
  • You can scale your office with as many SIP Trunks as you need. One or One Hundred.
