Another very important consideration to take into account is the ease of use of the teleconferencing system relative to the skill level and motivation of your employees. It have one thing to have a Ferrari, but if no can drive it is kind of pointless don't you think?

Therefore do not ever overestimate the amount of training, which is equal to the money and time and also opportunity costs in lost productivity in the short term, if you pick something that is way too complicated to be in use on a regular basis.

On a similar note to the ease-of-use, you want to make sure that the system is easy to install as well. I suppose this is relative to the quality of the technicians and the personnel that you have on staff. However, yes, you need to ask them to the review the system if it is feasible to install and implement seamlessly with the rest of the organization.

Most teleconferencing companies and services offer at least trial period for a while where you and your organization can test out the features such as durability, reliability, scalability, availability and ease-of-use during live test runs. This way nothing is left to the imagination- you know right away whether or not the system will work for you or not. If in the event there no qualified staff on hand to help you out, they may even provide you with a checklist of things to look for during your live test runs the will help you ensure that nothing slips through the cracks, and that you do not find any hidden surprises later on.
