I have one landline phone, can I use different extension number let say #1 me #2 wife #3 son

-> Response: For residential service normally you only have one extension. Businesses usually have multiple extensions for each phone but you pay for each one. If you have a cordless set you could intercom between each handset though.

I have always had WIRED LANDLINE phone service in my home, and am thinking of switching to digital phone service. I know NOTHING about digital, but have the impression that a "central" digital installation is plugged into my internet modem. If that is the case, what happens to my FOUR EXTENSION PHONES in other rooms than that central digital installation? I.e, with the phone jacks in the walls in the other rooms NOT receiving phone signals anymore (when I switch to digital), how DO they receive phone service, when the extension phones are as much as 25 feet from the room where the digital phone installation is plugged into my internet modem? (By the way, I have NO IDEA what "VolP" is!)

-> Response: Most people will use cordless phone systems for this very reason so you can still have multiple phones scattered across your home. Alternatively you can follow the advice in the article regarding the demarcation point at the house to isolate the external landline from your home and then use the VoIP adapter the VoIP company ships you to connect to the jacks in the house. I personally don't like that as it is riskier and often the adapter only has enough drive in it for a few phones. So most scenarios connect the VoIP adapter to your Internet modem and a wire to your cordless base and then use cordless devices across the house.

How do I disconnect my verizon fios coming into my house now that I use Spectrum VOIP so I can use my existing phone jacks for additional phones? I see the old wiring in the demarcation box but there is other wiring when verizon put in FIOS.

-> Response: It's a tough one to answer without seeing pictures. Also keep in mind that the ATA adapter that Spectrum likely supplied typically only has enough power to drive a few phones so this could be problematic even if you do figure out the wiring. My recommendation is to just use a cordless system instead of using the internal wiring.

I need 7 phones in my 2 story house. Cordless phones seem to be the answer. Do I buy the cordless phones separately or is there a package to get it all with one company?

-> Response: I would just buy the cordless phones from somewhere such as Costco and then connect the base to the adapter you will be shipped by your service provider.

3.5 acres with 3 buildings. Had everything hard wired to the ATA but lightning kept killing them (all wire was buried). Now using an ATA in each building on one network which is connected from building to building via a great wireless system, even video streaming works great. Problem is, I can call out from any building but lately I have stopped receiving calls or just not in the building that has the ringing phone. Any ideas?

-> Response: It sounds like maybe your VoIP provider is not supporting multiple registrations for incoming calls. In other words each ATA is acting as the same extension and successfully registering with the provider's servers. They are allowing you to make calls from any ATA but for incoming calls they are sending the call only to the first ATA that was registered.
You could test this by turning off two of the ATA devices and calling in from a cell phone. Do this for each building and verify that each test call works. If so then you need to talk to your provider as they may be able to fix this for you. If not I think you need each ATA set up as its own extension and a ring group for inbound calls that calls all three. This is more like a business feature though.

How can I use a cordless phone answering machine/base unit in the kitchen on the first floor when the VoIP connection is in the modem in the basement?

-> Response: When people do this they normally use a VoIP provider that has the Voicemail stored in the cloud and accessible from ANY cordless phone i.e. no need for an answering machine as the VoIP provider does this for you. Since all cordless phones can then access the voicemail, you can place the base in the basement and have a cordless handset in the kitchen.

At present my internet server buys bandwidth from a bigger company sells it at a cheaper price. My phone at present is with the bigger company that is ripping me off big time. I want VOIP so I will have my server still. It comes into the house downstairs, I have a filter and it goes to my modem/router and WiFi to the upstairs. Phones as I understand the master phone would have to be in the downstairs (NO) I don't want it there also I have one special phone for hearing impaired. I want to know how I can get this special phone hooked up upstairs and the master WiFi phone to be upstairs too.

-> Response: You could look at a WiFi Adapter that converts WiFi to wired Ethernet (under $30 on Amazon) and then connect that upstairs to the VoIP ATA (using wired Ethernet cable). The ATA then connects to your special phone using a regular telephone cable.


#11 : Posted by Steven R. Peters on January 21st, 2020:

So there is no reason a conventional base counter top phone - plugged into a VoIP ATA - cannot have extension phones around the house?

-> Response: Yes that's definitely possible. As per the article you just have to know what you're doing with regards the demarcation point. Unless using cordless phones in which case it's really easy.

How does the VOIP system work when the house is wired for 7 landlines phones?

-> Response: The adapter that the provider sends can drive a number of phones but 7 may be too many. Most people that need this many phones just use cordless phones and the adapter plugs into the cordless base.

I have spectrum voip with their phone modem connected to my cordless base unit with answering machine and 2 other cordless phones through out the house. But when phone rings and any phone is picked up all the other phones are disabled and if I wanted to be on a conference call I could not. Why is this happening and how can it be fixed?

-> Response: This may be a setting inside the Spectrum ATA device that needs to be changed. I recommend calling them. You should be able to use all 3 cordless phones though only for 1 phone call.

I always wanted a hamburger telephone and a coca cola phone growing up. I found one to purchase today, but I do not have a land line since I use VOIP with an Ooma Box. My house was built in the 95s so it has a lot of phone jacks and has one in my sons bedroom. I would like to purchase the hamburger phone for him but I do not know how to made it work.

-> Response: Yes the easiest option would be to buy the Ooma Linx wireless unit. Plug it into his bedroom and then connect the new phone to it.

I have an MRC voip phone system in my vessel. I need to install cordless phones so that when the phone rings in the engine room I can answer using the cordless phone. I have Panasonic phones and I tried installing but the phone is not ringing in the engine room. Do I need to install any adapter?

-> Response: Yes you need a VoIP ATA adapter (Analog Telephone Adapter) that the cordless base must connect to. Normally the VoIP provider will tell you which ones are compatible with their service. An example of an adapter is the Grandstream HT801.

I'm about to get a home DSL hookup for wifi in my house and am getting a voip line to plug my retro Trimline 210 phone into as well. I am 100% not interested in a wireless/cordless base with multiple handsets.
My question is this, I hope you can help! This is hard to research.
So, downstairs in my livingroom beside my couch will be my 210, the DSL wifi modem, and the phone modem thing. Upstairs I have another jack in the bedroom and have another 210 phone that I'd like to be able to use in the bedroom. I'm wondering if there is ANY way to make that second phone work with the bedroom jack. Some sort of adaptor? I don't have a landline by the way. I just moved here and have ordered the DSL with the ability to use a phone with it. (cell service is costing a fortune until towers built in approx one year or more). Hopping onto Wifi with my cell will save me regarding the much more costly data issue but the telephone issue is one of wanting multiple corded phones (1 extra in this case) with the modem being downstairs in the living room.

-> Response: Presumably you are only interested in having 1 phone line (i.e. use phone downstairs or upstairs but not both at same time).
Here's what we would do:
1 - Make sure no power is coming into your house on the landline - ask the DSL provider to check.
2 - When you choose a VoIP provider, they will send you an ATA (Analog Telephone Adapter). This ATA connects to your DSL modem via CAT5/6 cable and the 210 phone connects to the ATA phone jack. If you get a RJ11 splitter you can connect the phone to the ATA and also connect a new telephone wire to the jack in your house downstairs. This presumably will then connect to the phone wiring upstairs and simply plug your 210 phone upstairs into the phone jack. So now all phones connect to the ATA and then to the Internet. But only one can be used at a time.
3 - The ATA actually powers the phones (and through the phone wiring inside your house based on 2 above) hence reason you need to ask about item 1 as can't have power coming into house on the landline in addition to ATA trying to power the phone lines as that could cause problems.
Hope this helps.

But I need my POTS line to connect my computer to the internet (DSL). So likely not an option? Or am I missing something?

-> Response: You are absolutely correct, if you have DSL then this is not an option to you. My recommendation is to use cordless phones with multiple handsets, it is definitely the most popular way to do this.

Maybe you can answer my questions before I make the switch. I have four wireless phones and two land lines that are all connected to my router/modem through my cable service. Will my land lines phones work the same as it works now? As of the present I use Skype for all calls out of my local area and to Germany. Can I still use Skype or must I also switch my VoIP sever.

-> Response: When you say landlines you just means regular analog phones connected through your internal phone wiring yes?
Presumably your cable provider already disconnected the phone wiring coming into your house at the NID on the side of the house, in which case you should be fine. This is needed as otherwise you have live power on the phone lines from the PSTN side and the VoIP ATA (presumably this is inside the modem/router) also tries to power the internal phone lines. This would cause problems.
Making all of your phones cordless is likely the easiest thing to do but it should be fine with your current setup, so long as disconnected at NID.
VoIP is all IP based so you can still choose to use Skype and another (or more) VoIP providers. It is just Internet traffic and they distinguish each other by the port (e.g. 5060) and MAC address i.e. the physical address (unique) for each hardware element connected to the Internet.

I live in a 10 storey apartment building which is 30 years old. I want to get voip and since the building uses Bell cables I have been told I must get a dry loop.
The problem is that my computer equipment must stay in a specific room although I have 5 other phone jacks in the apartment. At present I have Bell service and my main phone is connected in the computer room with 4 satellite phones spread through the apartment.
I have been told 2 things. When they put in the dry loop in I may only be able to use one jack for the phone. Others say that all jacks can all be used. Doesn't matter how many ways I ask the question and I have asked a Bell installer, my internet provider and the VOIP company that I want to use.
Everyone says they can't tell me if I will be able to use the jack in my computer room. What has been your experience. The internet provider orders the installer to put in the dry loop but say they cannot ask them to come to the apartment to be sure the proper jack is working. The Voip service only sells the product and doesn't have anything to do with the installation and the Bell Installer that I talked to while he was working on another repair in the building couldn't tell me how to have the installation done correctly or even who to phone to have it done even if I was willing to pay for the extra service myself.
Do you have any suggestions of what to do.

-> Response: So long as you have Internet, VoIP has a chance. Use our VoIP test in order to check your current Internet (or future Internet if you need the dry loop DSL). The test will verify that you are capable of running VoIP on your Internet.
Assuming this is successful I would get some cordless DECT phones and the VoIP provider of your choosing should be able to send you an Analog Telephone Adapter (ATA). You connect your cordless phones into the ATA and then the ATA connects to the Internet modem and you are done. You won't need to use ANY phone jack in your apartment if you go down this path.
Does this make sense? I don't know why the Internet/VoIP companies didn't present this option as it's the most obvious one to me as it reduces your risk.

I have two(2) or three(3) MagicJack modules. Can I simply plug each of them into my network behind the firewall and use a different phone on each module?

-> Response: There should be no issue doing this as each MagicJack has a different MAC address so no issue with routing even if each MJ is on the same SIP port (e.g. 5060). Of course your firewall has to be able to handle this (i.e. port forwarding). Presumably you need 3 different phone numbers and this is why you are doing this, yes? I say this as it sounds painful to have a different phone hanging off each MJ. I don't know your requirements but one idea that comes to mind (if your call volume is relatively light) is to buy one IP phone that has 3 lines and configure each line for a different phone number and route them straight to a trunking provider. I say this as I wrote an article on this some time ago and it seems it might be of interest if you want everything to go through 1 phone instead of 3.

Wish I'd found this article before. I connected my ATA to my home wiring and ended up having to replace the ATA which cost me another $20!!
