| Panasonic DBS (Digital Business system) is the absolute best quality system I have ever worked with, however they no longer make this product. If you can find one that works well and it can be supported well, they are good. Overall I really loved it.
Nortel is another great system. I don't like the telephone sets as much as some others, but the smaller ones (like you would want) are fairly easy to program for installers, and with a little documentation, the phones are pretty easy for the users to use. The phones are pretty dependable, as are the systems. The only issues I have had with either of the above systems were from lightening strikes or the like, or end user abuse.
The 7316 sets should allow you to monitor all the lines, and if you add a DSS console (this gives you more buttons that can be programmed, so you can see who is on the phone and other on/off type info).
I used to work with Nitsuko, Oynx/TIE, and those were not as high quality as the Panasonic and Nortel. The phones were cheaply made and the cards seemed to glitch out more than other systems. They were also a bit more difficult to program. This is all my opinion (in lieu of a legal document LOL) |
