Use SIP to Pave the Way for Your Hosted PBX Future

Hosted PBX is the Future

Hosted PBX is your phone system in the cloud. For many businesses that require a no-hassle phone system with all the fundamental features, Hosted PBX is an easy decision. This will only become more so over the next few years as the old-style PSTN (public switched telephone network) finally fades away for good.

Hosted PBX uses internet technologies like SIP (session initiation protocol) to transport and terminate your voice calls. SIP is vastly more efficient and less expensive to use than older voice technologies like PRI. Depending on your current situation, you can save up to 50% on your current phone company line charges when you switch to SIP Trunking.

Migrating from On-Premise is Sometimes a Challenge

But for many businesses that have an on-premise PBX, transitioning to the Hosted PBX world can sometimes be painful. It’s a big change.

  • You’ll have to give up your old telephones
  • Hosted phones are menu-based and your old phone is button-based – it’s a bit of an adjustment
  • While hosted PBX provides powerful new features, it won’t work exactly like your old system
  • You’ll have a learning curve for implementing the new features
  • There will be a slight business interruption as you fine tune your new system.

These daunting challenges make it easy for many companies to put off making the switch. Their old PBX and analog lines ‘work just fine’.

But the change is inevitable.

Use SIP Trunking to Ease the Transition

You can ease the transition to Hosted PBX by replacing your old PRI or analog phone lines with SIP trunking. This is a very solid first step in your Hosted PBX migration plan because Hosted PBX providers use SIP technologies to transport your calls. Bottom line, you’re going to use SIP anyway so you might as well make the move to SIP and save some money while you squeeze the last few years out of your old PBX that’s sitting in your data closet.

Here’s how you do it.

Step 1: Place order for new SIP service
Step 2: Place order for new Internet circuit (if required)
Step 3: Design hosted PBX to meet your exact needs
Step 4: Place telephones and test
Step 5: Cut over to the new hosted PBX service


Company IT managers always need to balance technology change with cost control. When budgets are tight, it’s easy to put off migrating to a more modern voice communications system. The approach in this article is a good way to transition slowly but surely to a Hosted PBX solution and also save money while you do it.
