SIP Trunks don’t exist


It's a benefit of VoIP that multiple calls can occur simultaneously over a single broadband connection. This concept of the 'trunk' was borrowed from old PSTN technology and applied to VoIP so that VoIP providers could charge you more and you wouldn't question it because you were used to only being able to make as many calls at a time as you had lines. It seems most ITSPs these days do this, and sure, they've got to make money somehow, but if you have ever been confused by the concept of a SIP trunk, there's good reason - there's no such thing!A far more simplified way for VoIP providers to charge would be just per minute. If you've got one person on the phone for 10 minutes or 10 people on the phone for one minute, you would be charged the same amount, and no, you shouldn't have to have 10 'SIP trunks' to support the 10 people on the phone at once. That's not how SIP works!

You’ve probably heard that voice over Internet Protocol (VoIP) technology cuts telecommunications costs and improves productivity, among other benefits. It also provides useful features and capabilities that conventional phone technology can't offer. Yet with all the information out there about the benefits of VoIP, it may be hard to know what you don’t know.

Tristan Barnum, product marketing director for Digium Switchvox, highlighted the top five things you might not be aware of, but should know when it comes to VoIP, in a guest opinion we published over on our Unified Communications Edge site. Barnum also offers some expert tips for making any telephony system investment.
