Open Source VoIP Projects: DPN and Asterisk IP PBX Version 2

Last week, I pointed at Moshe Yudkowsky’s brililant discussion of disposable phone numbers (DPN). He’s put his DPN source code up at Sourceforge and added a bit of discussion of what you need to use the demo. For now, only Windows XP is supported, but Linux is coming. And apparently Voxeo gives developers access to a free number for testing. If this is your sort of thing, check it out.

And if that interests you, you’d probably be interested in the new Version 2 plug’n'play Asterisk IP PBX. This one is for Windows machines too. (Weird, and I thought a lot of the VoIP open source was focused on Linux.) It’s a turnkey Asterisk system, TrixBox, that runs on Windows XP and can support eight phone extensions using two lines, integrated voicemail, email notice of voicemail, and more. Additional phone extensions take only a few minutes to configure.

There are a ton of telephony features great for an SMB, including music on hold, call forwarding and transfer, and more. See Nerd Vittles for more details, including installation instructions and what you’ll need to run the software. (Computer, broadband Internet connection, accounts with two ITHPs - Internet Telephony Hosting Providers - etc.) Asterisk is open source IP telephony software that is based on the SIP open standard.
