PBX Comparison to Virtual PBX- Part II

Posted by Randy Kremlacek on Feb 21, 2012 12:17:00 PM

Find me on:

 Welcome to Part II of a blog series where I compare Virtual PBX and small business PBX. There are many variables to consider, but in the end, it has been my experience that it's pretty clear in the final analysis which of the business communication solutions works best for your particular environment. Let's get the thinking cap on and proceed.

Business Telephone Solutions

 

 Ongoing Administration & Maintenance

                  Virtual PBX                                      Premise PBX

 Maintenance costs for Virtual  PBX are less than the premise  PBX as you are only responsible  for the phones. The monthly  price that you pay for Virtual  includes maintenance on the  Virtual PBX. 

 You have maintenance costs for  the PBX and phones. However,  administration can be be quicker  with a premise-based PBX as  you can make the changes  yourself. 

 

 

Features That Help You Decide

                  Virtual PBX                                      Premise PBX

 The Virtual PBX is designed as  a “one size fits all” solution.  But  if you have simple call handling  needs, the Virtual PBX provides  more than adequate features.  It  may not have all of the bells and  whistles, but it meets the needs.

 Premise-based PBXes have the  edge in features and flexibility over the Virtual solutions. They  are designed with a high level of  customization available.

 

Your Vendor Relationship

This is one of the largest differences between Virtual and Premise-based solutions.

                   Virtual PBX                                     Premise PBX

 Virtual providers work from a  centralized office. They typically  do not have local representation.    You must install your own  equipment and test it. In the case  of a service problem you’ll have  only phone support. 

 Premise-based PBXes are  installed and serviced via a local  dealer. They pride themselves in  being close to their customers.

 

There is a middle ground where the anywhere nature of Virtual PBX meets local support. Some Virtual companies distribute their product through local dealers. This allows you to meet with the salesperson during the buying process. It also means that there is a local company who can assist with installation and service issues. Many organizations feel that the combination of Virtual PBX and a local support vendor is the ideal setup. 

 

Internet Bandwidth Considerations

                   Virtual PBX                                      Premise PBX

 Every phone call uses your  Internet connection(s), taking  80KB of bandwidth each. This  includes intercom calls. This isn’t  a lot of traffic but if your circuit is  small or already at capacity, you’ll  need to add bandwidth at an  increased monthly cost. 

 

 If your system is connected via a  dedicated voice circuit (typically  PRI), no data bandwidth is  consumed.

 However, the Premise PBX is  capable of routing calls via your  Internet connection using SIP  trunking. In this case, no  bandwidth would be consumed  for intercom calls.  

 

Okay, we've covered lots of ground here. In my next post we'll cover multiple locations (including remote pbx users), PBX disaster and prevention and communications security.
