I've been tasked with the possibility of upgrading our offices phone system.
Our current phone system runs off CAT3. Newer systems CAT5 or better. Our network is pretty old. I don't have CAT5 everywhere there is a phone and not even everywhere there's a computer. Those users end up on wifi. Anyway, from what I gather we can use a passthrough on the phones to connect the phone then the computer back to the network. We've got about 55 users and about the same amount of phones in our main office. Our plan was to also roll out VPN phones to multiple locations as we have jobsite trailers all over several states.
Is it advisable to use the passthrough on these phones? Or is having a dedicated line going to be significantly better? We also have a few places in the building where I've had to add a few small switched and I'm concerned we'll get some call degradation because of this.
Like I said, our network is a bit older and a lot of it has been band-aid fixes by adding some wifi AP's and daisy-chaining a few small switches in some areas for additional personnel over the years.
Personally I'd love to have our building rewired but I'm not totally sure it's necessary, however I don't want to cause more problems or increase load on a network that's barely adequate as it is.
If you need more info from my I'd happily provide it. I'd like some advice from anyone else who's done similar upgrades or implemented phone systems on current networks.
