Good Afternoon

Maybe a bit of an odd question but as I've alluded to in other posts I'm in the process of swapping out phones form our legacy PBX to voip handsets on a hosted could solution.

We have some phones that are wall mounted and I've found with some that getting a standard cat 5/6 cable into the back of the phone and getting it flush on the wall is not easy.

Would cutting an old phone cable and putting RJ45's on it in a 10/100 pin out work?
Probably 30cm/12" or less just to get form a socket in the wall out to the handset?

Thanks

Grant

What is the wiring itself? Is it like, old 4 pin telephone wiring?

For a very short run like you mentioned, i'd assume it would work, since I've seen some flat fairly short ethernet cables that I don't believe have the twisted pairs inside them, just straight through. If it was a longer run, the twisted pairs inside the cabling are important.

They also sell very thin cat6 cables that might be a better option, something like this

(I saw in another post you're in the UK, not sure if monoprice ships there or if theres another vendor that you could get them from).

Or if the ethernet cabling is already inside the wall going to an RJ45 wall plate, remove the plate and crimp a connector directly onto the cabling?
