| VOIP over Phone Line Networking?
I just had a thought.
I know, the best way is to just install CAT5e or CAT6, and jacks into the walls. But some of us don't have that option, since some of us live in apartments, or other situations where it's not possible to easily install CAT6.
So, has anyone ever tried to say, use a VOIP phone with Phone Line Networking? Or is there some technical issue that makes that undesirable? |

| No sure if I really understand your question. You don't have to use cat5e or cat6 for voip. You plug the voip adapter into your router or straight to your cable/dsl modem. The "Phone" portion plugs straight into the voip adapter. Most people who live in apartments; small areas; rentals where they can't wire their jacks into the voip adapter; etc... usually use cordless phones. Plug the cordless base into the voip adapter and then use the cordless phones. What are you wanting to do with cat5e or cat6? Treat your voip adapter just like it was another PC on your network. Please clarify what you're trying to do. Thx... Mike.... |

Maybe the OP wants to use existing PSTN phone wiring to connect multiple POTS phones around the apartment to a VOIP adapter? |

The idea was to have a VOIP phone, such as the Aastra 57i or a Grandstream GXP2000 in a room such as the living room, which has no Ethernet jacks or anything.
The idea was to use Phone Line networking to connect the VOIP phone to the rest of network with phone line networking.
This is because in an apartment, I can't just tear up the walls and install CAT5e or CAT6 cable.
I wondered if phone line networking would introduce unacceptable latency, or other nastiness. |

Scratch that hypothesis. Phone Line Networking is described here. It appears to be a technique for running an Ethernet over analog telephone wiring.
Maybe the OP wants to use Phone Line Networking to set up an Ethernet around the apartment? If it worked, it would be possible to plug, say, a VOIP adapter into the network at a place remote from where the Internet connection enters the apartment.
OP, please tell us more about what you are trying to do.
Edit: we had a race condition. You posted the answer before I posted the question.
I don't have any experience with Phone Line Networking. Maybe a wireless router would achieve the same result, albeit with weaker security. |

They actually make Wireless/Cordless ethernet jacks. That would be the simplest. 1 end plugs into the wired jack of the router and an electrical outlet. The other end is plugged into another electrical outlet of your choosing and you plug your device into it. Much simpler.
The problem with using the phone wiring is that in an apartment, you probably don't have access to the NI or dmarc/66 block; and therefor can't disconnect it from the telephone company. If you plug into the phone wiring and don't know what you're doing, you can possibly put voltage into your equipment and fry it. And if you mess up the phone wiring/NI, you will be responsible for paying to repair it.
The simplest thing is either cordless extensions or using the wireless/cordless ethernet jacks. You can also use a wireless bridge and connect back to a wireless router if you have one. There are a lot of options. But if you don't have the access or the knowledge, I would stay away from the telephone wiring. Especially in an apartment where you can affect the other tenants and get yourself in trouble, later... mike... |

1 edit | Ya, HomePlug AV would be much better than the essentially dead PhoneLine Networking.

Another solution would wireless using a wireless bridge for IP phones.

Phone line networking works fine. I have actually had better luck with it than either wireless or the powerline (HomeNetwork AV) equipment. Power lines tend to be noisy and so transmission speeds are slow. Powerline networking may not work if the electrical is shared between apartments (so called Coop apartments with only one meter for many apartments). They can also be a security risk as the signal may leak past the meter and could be intercepted (highly unlikely) by someone on the same power grid.
Wireless does not work well in old rowhouses or any house with lead based paint. The only time phone line networks fail is if the wiring is already being used for another phone line networking equipment (say for an alarm or integrated smoke alarm setup).
Just make sure that you don't use any of those DSL filters on the line that you want to use phone line networking since the filters will disrupt the connection.
And as a last resort, I have even used point to point, directional wireless repeaters to get a connection. But that is a very expensive option. |

I have a laptop on a HomePlug AV - works great!
A little pricey, but it beats routing cat5, or messing with wireless routers. |

Phone lines work great; UNLESS Ma'Bell left the voltage on the lines when you disconnected service. (Very common: Especially in apartments where people move in and out of regularly). Or, even if the voltage is gone, it can still be connected thousands of feet back to a cross box or the C.O. Phone lines are only good if you can disconnect those lines from the NI where it enters the house. Being an apartment, you probably don't have access to that. Go for it if you want; but know what you're doing.
P.S. And the wireless options given will work great. You aren't dealing with large distances, so paint and such isn't an issue. And many wireless/cordless ethernet jacks are truly wireless and don't use the electrical power to transmit the signal. Just to power the adapters. Just like anything else requiring electricity. later... mike... |
