ok, here's the deal http://www.techspot.com/vb/images/smilies/smile.gif

standard network;
each pc has a wallplate with 2 x rj45 sockets, one connects to the pc to allow network/internet access, all standard stuff really.
The other is required for voice, whereby the pc user just plugs their phone (http://www.techspot.com/vb/showthread.php?p=722036#) into it and it works, enough said.
Now the comms rack has just a 24-port data switch at present and the telephony people have just installed a live phone line and thats it.
So, what is needed to allow the 2nd rj45 port to be used for telephony (apart from phone handsets http://www.techspot.com/vb/images/smilies/wink.gif?)
A voice panel of some sort? some kind of convertor?

Any and all advice appreciated.

Are you just using it with a standard phone and trying to use the existing network cabling? If you are, you just want an RJ45 to RJ11 adaptor on both ends. One to convert the phone plug into RJ45 and then the other to convert it back so you can plug it into the phoneline/internal exchange etc.. :)

Thinking about it thought, i'm not completely sure you'd be able use a basic one through a switch.. But the principle is the same :)

I think Aaron is right, we have these on the ends of all our phonelines at work.

Yeah, i've used them alot before too, but they've always terminated at an internal exchange/phoneline or just basically used the cat5 as an extension cable.. Not really ever used them through a switch/router, and i'm not sure if it would work - I would imagine to use it with a switch, it would have an address/ip/some sort of ID? I guess it would have to be an active converter rather than a passive one? If that makes sense?

Phones in the corporate invironment do use Data switches.

BUT they have an Active adapter called a Modtap.

Make sure the telephony "service" is turned on/is on manual setting rather than "disabled" :D:D


Just in case. ;)
