An anonymous reader writes "Today at Astricon (the first Asterisk conference), Mark Spencer announced the release of version 1.0.0 of Asterisk. For those of you that don't know: Asterisk is a complete PBX in software. It runs on Linux and provides all of the features you would expect from a PBX and more. Asterisk does voice over IP in three protocols, and can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware. Asterisk users can be up and running, making phone calls in under an hour using the various guides found at the VoIP Wiki. Connectivity to the PSTN is provided by companies like VoicePulse, Nufone, Gafachi and VoipJet."
