I have a SOHO setup with about 8 computers/laptops/servers on a LAN and a regular ADSL internet connection over the phone line. There is no EPABX. Just a regular phone line (after the DSL splitter).
I'm using a Cisco ADSL Wifi Router WAG54G2 along with an D-Link 8-port switch to hook up all computers.
I chanced upon 4 free Cisco IP phones from another organization that was shutting down. These are slightly old. The model number is CP-7940G.
Whats the minimum hardware I require to hook up these phones on the LAN and the phone line. There are three ports behind the phones. I don't really require extension numbers, but I'd just like to use the IP phones instead of the regular phones.
There are three ports behind the phone.
Any help is appreciated.
