It’s not always cheaper to use VoIP

Since a call is traveling over the Internet, it must be free, right? Well, not necessarily. Just like paying a flat monthly fee for local telephone calls or a per-minute charge for long-distance calls, dialing over the Internet can come at a price whether direct or indirect, which may or may not be cheaper than the 'standard' PSTN (public switched telephone network) service. Cost also varies according to your call scenario. For instance, calling VoIP-to-VoIP within the same network can in fact be 'free' (think Skype to Skype). However, when a VoIP user calls a non-VoIP user (think: VoIP call to a cell phone), the call leaves the VoIP network and 'terminates' into a regular public phone network where it is subject to regular fees. The difference is also a matter of WHO you're paying and not just how much. If you are using a VoIP carrier or an ITSP (Internet telephony service provider) with 'termination' points all around the world, the cost to call internationally or long-distance, for instance, can be significantly cheaper than a traditional carrier. However, a VoIP call from New York to a non-VoIP user in London will not necessarily cost any less than dialing from a 'standard' phone. The bottom line is that it isn't an all-or-nothing approach when it comes to VoIP.

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.
