IP Phone with a Analog Home Phone Line (Rj-11)
Posted on 2016-10-01
I'm looking to see if it's possible to swap out my analog phone with a Cisco IP Phone (E.g. Cisco 8851). I have a home office and only have a analog phone line coming in through Time warner cables (TWC) router. TWC doesn't allow me to switch directly to a VoIP connection, but instead I have to get a standard analog line out of their router. My company will give me the Cisco phone if I can get the line to work. I'm so use to using Cisco phones and headsets, and since I work remotely often enough, I want to be able to use a similar phone at home. Is this possible?
I've looked into ATA boxes but can't seem to determine if it can be used for my situation. It seems that I can connect a rj-11 to it and connect it to the network, but all examples I find seem to connect the connector back to the network or another computer. Some places say I need a "Cisco Voice Gateway with an FXO port running Call Manager express, connect your home line into the RJ11, FXO port and register your IP Phone with Call Manager Express."
