Just how dependable are Cisco voice over IP solutions?  This uncertainty is why many people get concerned when they find out they will be using a phone that is attached to the data network.

These concerns are rooted in several sources.

• Historic network performance – computer networks in general have the persona of being somewhat reliable.  Many consider the performance of an Internet connection as what they could expect of a new IP phone system. It’s the “somewhat reliable” that causes concern.


• Perceived network performance/PC performance – websites, applications or the PC appear to be sluggish at times.  While this could be due to any number of factors, to the typical end user, this is the network.


• Reliable phone systems – there is no doubt the telecommunications industry has created traditional phone systems that are extremely reliable. This minimizes the need to switch because they don’t understand the benefits beyond dial tone.

There is an industry joke that if a network engineer maintains a data network with 95% uptime, he is a hero.  If a telecommunications engineer maintains a telephone network with 95% uptime, he is fired! 

However, given the advancements that Cisco has made in this technology space, systems can now be designed and configured to provide better reliability than traditional phone systems.  The very basic concept of IP telephony allows for tremendous flexibility, scalability, and more importantly, reliability. 

Traditional phone systems have all the functionality built into the PBXs – configuration, call processing, call routing, voicemail, PSTN connectivity, and handset connectivity – to name a few.  IP telephony breaks these functions out into separate devices that can be dispersed throughout the network, as well as duplicated to provide redundancy.  Now you can have a voice gateway with PSTN connection in 2 offices and provide backup PSTN connectivity to each site or have call processors in the 2 locations to provide backup call processing and call routing to ensure that you always have the ability to send and receive phone calls.

Aside from utilizing redundant equipment, most recent voice server applications use the concept of active and in-active partitions.  This now allows for more efficient upgrading of the application but also a fallback plan if the new upgrade doesn't perform as expected – all with minimal downtime (recall that we are using redundant equipment as well!)

Cisco’s latest development has been to move the voice application servers to a virtual environment.  This not only reduces operating cost, but also provides a robust platform for streamlining the deployment of voice application servers making the switch from a traditional telephone system easier than ever.

So what are you waiting for?  Find out how your company can benefit from Cisco Unified Communications today!
