step 1 locate a sip phone adapter without a carrier
step 2 locate a non wireless phone and plug it in
step 3 now if you have a Asterisk PBX server access its Directory and set up username and a extension and a location (location is the sip phone adapter ip)
then when you start to use your sip phone adapter you need to access its system and set its connection over the internet by setting the ip and port that you will connect to (this case its a pbx asterisks server)
step 4 now this is where i had a lot of help from a hourly Adjunct he opened a socket for me and had me set up a open socket on my computer at home which i did just dont recall how at the moment
step 5 once this is done you can now dial a extention from the phone attached to the sip phone adapter to an extension that the asterisk sever can see
step 6 if you were able to to follow the instructions above and with some background knowledge you will have heard a voice or in my case wild monkeys
