NOTES

Clients can be connected to more than one service at a time, think of it as having 2 seperate phone lines, both connected to different providers but both phones plugging into one unit.. so feel free to sign up for accounts at more than one service.. you can select which service you want when dialling away from the default service by starting to dial your numbers with #2 for the second account you have setup etc.

SIP is the new protocol used to initiate communication between various units, and it is a standard met by clients on linux, windows, or on stand-alone voip phones. This means you can call any user on the network not caring what kind of hardware they are using, the SIP should help start a common conversation so you can talk to each other.

Simple trying out VoIP

Get yourself a client from the links listed at the top of this page, if you find any other clients please add them to this list, or if you want to point out problems or good points add them to this list also. install this client and set it up to work with a SIP service, i recommend FreeWordDialUp? simply because it was the first i tried and was simple enough to get going. set the options as the FreeWordDialUp? page suggests, using your password and login number (this login number is your phone number) and hopefully you will register to the network. take a look here for samples on how to setup your client http://pulver.com/fwd/quick/ FWD has some handy testing numbers to enable you to test that you can dial out correctly. so try these numbers to check your client is working correctly.

place a test call. For your first call you can try calling the FWD Welcome Phone, FWD# 55555. 55555 is staffed by members of the Free World Dialup Community. This is not a "help line."

You can also try calling the FWD Answering Machine as FWD# 10001 or ringing FWD#10000, the phone on Jeff's desk.
