Phone line over the network?

I have two buildings which are connected by a single cat 5 cable.

I have phone service in building A, but not B.  Is there a device that would allow me to plug a phone into the network, at location B and carry voice over the network to location A?

The goal is to use my phone line at both location A and location B over the network.

Thank you

What sort of phone service do you have?

How many phones do you want at location b?

I don't think its worth the expense of converting voice to data and then the data back to voice to go into a phone system.

you can get a vonage box which allows you to use a normal phone over the internet at a very low monthly cost.
see www.vonage.com

if the single CATv cable is not used for the internet then you can dedicate the CATV to the phone by buying convertor sockets at each end of the CATV cable - cbasically it converts CATV to RJ45 (the telephone plug standard) in the UK there are the following adapters:

hello,
If you have a Cat 5 cable between two sites, this cable can not be more long than 100 mts. If you want only one extension and don't want a 1Gb link (10/100 Mb only) then you can use pins 4 and 5 for a phone signal, but if you want a more professional solution consider to link two buildins with a Wifi network if order to obtain a VoIP channel with a 5 connections with a good quality. 3Com, Cisco and D-link will be a good entry point.

A couple of these would do the job :-

It will plug into the analogue line and transmit the voice over the normal network to the box the other end where you can have another normal phone connected.

chilternPC is correct but I assume you are asking because you want to only have one phone number.

I agree with joe as to the other pins.  If the network cable is being used for data you only use 2 wire pairs and could use another paid for analog phone as well.

The orange and green paid are used for data so you could use the blue paid for the analog phone.

This is not the ideal way, but it will work.

Hi grblades:
I can't see having 2 of these working ?
where does it say they can be used like that?
the  Linksys SPA3102 NA   is basically the vonage box rebranded -
and I have one on my network and they can't talk to each other?

Primarily I was going by the last paragraph in the link I gave
"A typical user calling from a land line or mobile phone will be able to reduce and even eliminate international and long distance telephone charges by first calling their SPA3000 via a local phone number or by using a telephone connected directly to the unit. The advanced authentication and call routing intelligence programmed into the SPA-3102 NA will connect the caller via the Internet to the far end destination with security and ease. Using the SPA3102 NA at the far end, calls can be answered immediately or further processed as a local call to any legacy land line or mobile phone allowed by the SPA-3102 NA dial plan."

The 1st part of the text above indicates it can accept an incoming analogue call from the pstn and send it over voip.
The latter part sais it can accept a voip call and pass it to a local extension.

Configuration wise you should be able to configure them with the other units IP address as the gateway with identical usernames and passwords. All calls should then be forwarded between the two.
