is it possible to convert an ethernet connection to a phone connection?

Hello and Good Afternoon Everyone

              I have a storage closet at work which has an 2 active ethernet ports.  However, I could not find a regular telephone port on the wall anywhere.  I am interested in connecting a regular telephone within this storage room which brings me to the point of this question.  Is there a special chord which can interface a telephone with an ethernet port?  

               Any shared ideas or thoughts regarding this interest will be greatly appreciated.

               Thank you

No. You can use the pairs in an Ethernet cable to connect a phone jack to a phone patch panel.

If it's an analog phone, simple use pins 4 and 5 as your twisted pair.  If you have 2 pair, 3,4,5,6 will be the correct pins.  RJ-11 will fit into an RJ-45
Chris HInfrastructure ManagerCommented:
RJ-45 is 8 wires, RJ-11 is 4 wires, but the 4 wires of RJ-11 overlap exactly with pins 3,4,5,6 in RJ-45

Echoing Choward, yes, you can plug a phone into the ethernet jack, but you have to do something similar at the other end in order for the phone to actually work. And you have to be a careful, since plugging a live phone line (which carries 48VDC) into a live ethernet port is almost certainly going to damage equipment.

VOIP phones are ethernet devices, on the other hand, but similarly need infrastructure support at the other end of their connection.

you can use the lan cables to get out of the room, but in the end you need to connect it to a regular telephone line, of course

Hello and Good Morning Everyone

              Thanks so much for the replies given in response to my question.  After reviewing everyone's shared input, it seems like the easiest and most straightforward approaching to connecting a regular telephone line into an ethernet port would be to use the suggested device given with Eirman's link.  However, I do have a simple followup question about the links http://www.ebay.co.uk/itm/RJ45-Male-to-RJ11-6P4C-US-UK-BT-Female-Jack-Socket-Telephone-Connector-White-/390942920037?hash=item5b06038d65  and http://www.ebay.co.uk/itm/RJ11-Male-Plug-to-4-wire-RJ45-Male-Plug-Flat-Cable-Lead-1m/271952614710?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140122125356%26meid%3Dfcf17c389b8f4481bfee53151c25858d%26pid%3D100005%26rk%3D4%26rkt%3D6%26sd%3D390942920037.  Since I live in the United States, could someone post an online purchase link of this same interfacing device?  

Thank you

Here is an Amazon link:

Remember it does not allow you to patch a phone into Ethernet, rather you may need one at each end to use Ethernet cable as a phone cord replacement.

Cheers.

URBEST®-Female-Telephone-Ethernet-Adapter — since you'd want a pair — might be a cheaper alternative.

But read the reviews...a lot of people appear to buy these without much understanding of what they can and can't do. They are passive devices, and simply pass through the two pairs 4-5 and 3-6. I'd argue that you don't need them at all, since the rj11 plug fits in the rj45 jack,  connecting the same two pairs. You would never plug one of these into a router or switch or into a jack that's connected to Ethernet equipment at its other end.

I'm getting that this isn't a VOIP and just a simple POTS or analog line.

What I'm telling you is, if you use RJ-11 at both ends to connect the phone into the RJ-45 jack, you DON'T NEED ANYTHING.

Think of the jack as 8 wires on both ends, your phone plug will touch the center two or the center 4, depending on the configuration.  The ethernet, as long as it's just a cable run and doesn't go into an piece of equipment that amplifies or routes the signal, is just a medium for carrying that signal.  No adapter would be required.

Hello and Good Morning Everyone

               I want to sincerely thank everyone for their shared insights into my wish to connect an analog telephone using an RJ 11 chord straight into an RJ 45 connector which is normally reserved for ethernet connectivity.  At this point, I request an extension given to this question by a moderator in all fairness to the people who have responded to this question because the recommendations given have not been tried yet.  

               Thanks in advance everyone for your indulgence and patience with me regarding this question.  I will report back soon on my progress in addition to the strategy chosen to resolve this issue.

Hello and Good Evening Everyone

           I have decided to use the converter suggested within the link provided by Eirman.  This seems like it will be an easy to follow and straightforward approach to what I am trying to accomplish.  

            Thanks again everyone for your suggestions.
