Thanks in advance to those of you with relevant expertise and experience for taking the time to respond to my post.
We are a financial services firm in California. We have three offices connected by P2P T1 and we currently split voice and data on those T1s. We have a Toshiba DK series system that we want to replace with a more modern, easily supported and feature-rich system.
We are definitely interested in VoIP, so long as it will prove reliable and survivable.
Our network is pretty basic, with Cisco routers and Dell switches. Our cable plant varies at each location from Cat5E to some old Cat5 that predates the modern standards for Cat5 installations (thus, out of compliance).
We recently renewed our lease and are entering into a large tenant improvement project in our main office. This is where all the old Cat5 lives. We need to make a decision this week as to whether or not, and to what extent, we will need to re-cable our main office. The price to do a complete re-cable job is a very hefty sum, and based on our current requirements, the only thing that would drive such a step is the need to meet spec for a VoIP system.
So I'm looking for some advice from the pros as to whether or not pursuing VoIP is really worth it considering our cable situation, some general tips on how to go about selecting a new phone system these days, and what to watch out for along the way.
