Do I need an Ethernet hub, switch, or even a router to have my Ethernet VOIP telephony box to be hardwired "separately"...?


Hello. Do I need an Ethernet hub, switch, or even a router to have my Ethernet VOIP telephony box to be hardwired "separately" from my cable modem and NOT be part of my hardwired wireless router's ports???

My Objective/My Plan:

This is for home/residential networking. To have two (2) hardwired networking hardware items: 1. (1) VOIP box... ...and... 2. (1) wireless integrated router BOTH hardwired off of the same cable modem of my cable ISP. I need either a hub, a switch, or even a router to connect both networking hardware items to the cable modem. Also, I MUST BE ABLE to connect to the Internet at the same time for both the VOIP box and the wireless integrated router (the Internet) if necessary. My current wireless integrated router will serve as my wired/wireless networking device for a desktop computer, a laptop, an Internet streaming radio, and a Wi-Fi Smartphone; but the wireless router *WILL NOT* serve my VOIP telephony service. Why? See: "Reason".

[*NOTE: I have learned that a two-way Ethernet "splitter" allows two (2) computers or other networking devices to share one Ethernet line, but it doesn't support both networking hardware to connect onto the Internet simultaneously or at the same time. Therefore I cannot use an Ethernet splitter since there will be MANY times I am online AND on the phone AT THE SAME TIME. I can only consider an Ethernet connectivity options like "hub", "switch", or "router". Yes, the splitter is the cheapest idea, but not an option!]


Why my VOIP box MUST BE INDEPENDENT or SEPARATELY hardwired from my cable modem and not hardwired to my current wireless router? I NEED to separate the VOIP box from the router that serves the rest of the networking setup hardware I have. Why? I'm prone to many electrical storms where I live, it would be best to unplug a power strip plug for ALL my networking hardware and a commonly shared Ethernet port/cable connection between the modem and the wireless router serving my networking hardware for safety and protection from damage from an oncoming electrical storm. Also, when I am out of town where I STILL NEED my household phone service STILL ACTIVE; this setup would STILL KEEP my phone service active while I am gone and still the rest of my network hardware would literally never receive any damage from electrical storms. Unequivocally, I have learned unplugging everything IS ALWAYS THE BEST option; undoubtedly better than surge protectors. Yes, the risk is relatively "small" of damage with connected surge protectors for electrical power and even lower for incoming data transmission damage; but again, totally unplugging the MOST POSSIBLE networking hardware is THE BEST BET!

For your information, the VOIP box offers an incoming Internet connectivity, an outgoing traditional telephone jack, and a power port for a power adapter. No Internet bypass Ethernet port on the VOIP box.

Another Potential Router:

Okay, I bring up a "router" (actually an "integrated" router) in my question as a possible option for connectivity between the cable modem and the VOIP box/my current wireless router to serve as a hub or switch. I would also have to use another one of this potential router's Ethernet's outgoing wired ports to connect to my current router's Internet incoming port of course. The new possible router would connect inline between my cable modem and my VOIP box/current router, where then my current router that would be connected to all my networking hardware. You may consider another router as overkill here for the sole purpose to serve as a hub or switch for my VOIP box, but I am also not aware that I may have networking issues with another router when I ALREADY HAVE a router as part of my home networking hardware? I have been finding the cost of an Ethernet switch is about the same as a fully integrated cheaper home router that has the typical 4 wired ports. I am thinking of getting a cheaper "sacrificial" (for electrical storms) router, such as the Netgear N150 (WNR1000) router or the Belkin N150 (F9K1001). Yes, I am ONLY USING IT for the WIRED purposes, the Ethernet wired ports connection only for VOIP and Internet. Is having a router as an option to serve as a hub or switch not necessary and overkill or not really? Is having two (2) routers inline a serious cause of networking issues? Can this possible router be "tamed" in such a way as not causing networking issues?

Questions to answer please:

1. What do you think I need? Do I need an Ethernet hub, switch, or even a router to have my Ethernet VOIP telephony box to be hardwired "separately" from my cable modem and NOT be part of my hardwired wireless router's ports?

2. Will an Ethernet hub or switch support more than one networking hardware to connect onto the Internet simultaneously or at the same time or not? (I am not familiar with Ethernet hubs' and switches' properties.)

3. Another router a "fair" idea or do you not agree at all for an integrated router to serve as a hub or switch? Will I have networking issues if I incorporate another router into this setup? Can it be "tamed" to not cause issues?

4. Do you have any suggestions, different ideas, or thoughts here?

Thank you!

  1. If you are using the same ISP for your internet and VoIP, then you only have one ISP Modem, correct? What I'm getting at is that your cable modem is always going to be on? So, we have the Modem (Internet Access)- "A", your computer/s and or other wired devices- "B", and you have your VoIP phone- "C". Now, depending on your Internet Service Provider, you should be able to connect your "C" to "A" without having to worry if "B" is connected. How many Ethernet ports does your "A" have? If it only has 1 then you'd need a simple Fast Switch Ethernet Hub- "D" to add at least 4 more Ethernet ports at almost no performance loss. Then you can connect "B" and "C" to "D" and then connect "D" to "A" Now, all you have to do is disconnect "B" and leave "C" connected. Am I understanding this correctly? If your VoIP requires an internet connection, and you only have your one Modem, I don't see how you can get around not using it? I swear I've reread your problem several times and I don't understand what your problem is. Is it that you fear it getting struck by lightning or that your network is failing?

  2. Hello rsktek:

    Nice to meet you.

    This was not a "problem" per se, just trying to find the "best" way or practice of a device "Ethernet hub, switch, or even a router" to simplify the hardwired Ethernet connection for a quick and easy disconnect (for electrical storms) and yet still have my VOIP service always active. On the onset, I really didn't know at first what I needed in terms of hardware to achieve my plan or my varied options I had -- like an ethernet hub, switch, or router. I still wonder if an integrated router that has switchable ports on it could also be used like a hub or switch since their costs are rather close in comparison depending on the retail outlet I determine? That is why I approached this thread as an inquiry on potential methods (seeking the best method) and what I should use to connect rather than as an issue or problem.

    No, I didn't say... ...but my cable ISP is NOT the same as my VOIP. They are different companies. But that really does not matter in terms of setup since teh VOIP box needs constant Internet signal.

    So YOU suggest that I use a "hub". Okay, great. I will have to look into that.

    I am just curious as to the integrated router as the brands and models I indicated in my OP?

    I am open to more ideas from other members too.

    Thank you!

    Ok, I think I understand your request but to recap: You want to be able to take everything except your ISP modem and VoIP box offline at any time. rsktek asked an important question that I think I know the answer to, your ISP modem, how many ports are on the back? If it's 1 (which I think it is), you'll need a router between it and your VoIP box. I would recommend your hook it up as: Modem>Router>1. VoIP box 2. Switch to rest of network. In the event of a storm, you could unplug the switch to protect everything downline exposing only your modem, router, and VoIP box.

    Also, make sure the router you use does not incorporate SIP ALG or at least can be disabled. SIP ALG can cause problems with hosted VoIP solutions.
