Cost saving is one of the main reasons for many businesses and enterprises to move to VoIP. For businesses that deploy SIP trunks, it may be tempting to cut corners by using lower cost network elements, or by omitting some devices they considered “non-essential” but nice-to-have.

One question we often hear is “Why can’t I just connect my IP Phone or IP PBX to a SIP trunk?” Well, to answer that question, let’s take a look at the risks you are exposed to without an extra protection.

learningWhen we first learn that Elastix had suffered an untimely demise, we were a little surprised. The good folks at Palo Santo had built a well-known and loved the platform that seemed to do all its capabilities. Elastix’s popularity was widespread across the globe, which now causes a problem for those still using a platform that’s no longer commercially supported.

While you can still download, install, and use Elastix, you won’t be receiving any updates or security patches, and for businesses that rely on VoIP technology as a critical service, that’s a big problem. Thankfully, our friends at Sangoma created a script to move your Elastix configuration to a new installation of FreePBX, for those of you considering it as an alternative. This is possible …

This happens all the time in our everyday lives. As much as I’d like to blog about the time I actually needed to use a check to pay for something, we have to stick to the world of VoIP!
