The two major protocols used for VoIP are [SIP] and [H.323]. (They are completely different standards, not related to each other). SIP isn't so much a complete VoIP protocol - other protocols are required for the actual voice data transmission. See the [SIP] page for more details.
[Cisco] also deploy [MGCP] and [Skinny] on their AVVID solution.

!!NOTES
Clients can be connected to more than one service at a time, think of it as having 2 separate 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 FreeWorldDialUp simply because it was the first I tried and was simple enough to get going.
