Hi, I have an office with 20 phones, we are implementing a new VOIP Trixbox phone system but trying to save costs on the cabling.
The old phones are running on CAT3, would it be possible to use the current CAT5e cabling by splitting the pairs?

Thanks,
DM

I assume your new phone system is using digital phones but not IP phones. If that is the case, you can use the CAT5e cabling for them. I would leave each cable as is, though. You can even leave the jacks as is since the phones should be able to plug directly into them. They will simply use the pairs that they contact and ignore the remainder. This way the cabling in place retains its flexibility for future use if you decide to use it for data at a later time. If you are, by some chance, using IP phones or anything requiring PoE then you should verify that the cabling supports that, though.
