If you have just one computer in your house, the computer may be connected directly to your modem by a 

cable. In this case, you do not have a router.

If you have multiple computers in your home, or if you have wireless Internet access, you have a router.  A 

router splits the Internet connection into multiple connections, or ports, for your computers to connect to. 

Most routers have four (sometimes more) Ethernet ports on the back panel. Routers can connect directly to 

computers with a cable, or indirectly through a wireless connection. If your router makes wireless connections, 

it may have an external antenna. To find your router, look for a device that has one Ethernet connection to 

your modem, and multiple connections to your computers or has an antenna.

Integrated Routers
In some cases, the modem, router, and wireless transmitter are all combined into a single integrated device. 

In this case, you will have a single device with one connection to the DSL or cable wall jack and either cabled 

connections to your computers, wireless connections through an antenna, or a combination of both.

Identifying your phone system is the easiest part.  If you have more than one line or phone number in your 

home, you need to determine which wall jacks work with which number to ensure all your ooma devices are 

installed on the same phone line (the line which you registered your ooma system). If you have more than one 

line, you will have either two-line splitters or dual-jack wall plates that allow you to connect to different phone 

numbers. 

Splitters
Telephone splitters are small devices that plug into a telephone wall plate and split that jack connection into 

two jacks. There are three kinds of telephone line splitters you might find in your home, single-line splitters, 

two-line splitters, and dual-jack wall plates.
