SippySkype SIP-to-Skype Gateway

Last month I wrote about my strong disagreements with a guest blog post on Skype Journal that was titled "A SIP/Skype Gateway Is NOT In The Forecast". I disagreed with the premise that a SIP/Skype gateway isn't in the forecast. Well, Skype Inc. may not care about offering a SIP-to-Skype gateway, but that doesn't mean VoIP enthusiasts are going to sit around and not build their own SIP-to-Skype gateways! I've blogged on a few occasions where I discussed the desire for Skype users to have SIP connectivity and various home-brewed solutions.
\n
\nWell, we can add another SIP-to-Skype gateway solution to the mix. I just discovered SippySkype today, which is an open source & free SIP-to-Skype gateway.
\n
\nCheck out the features:
\n

\n
• SippySkype is Java software that allows you to make and receive Skype calls from your SIP/VoIP adapter. Basically a Skype/SIP Bridge/Gateway/Proxy
\n
• Call Skype Users using speed dial or use Skype out.
\n
• SIP to Skype authentication/denial mappings via SIP caller ID and IP blocks - 1.1 or higher
\n
• Skype to SIP authentication/denial mappings via incoming Skype User ID - 1.1 or higher
\n
• Support RFC2833 touchtone decoding (DTMF) - 2.0beta or higher
\n
• Could be used as an endpoint with Asterisk
\n
• Auto play pre-recorded file(s) to SIP callers - 2.0beta or higher
\n
• Incoming SIP Pin number authentication and dialing - 2.0beta or higher
\n
• Open Source - You can modify/fix it if you like.
\n
• It's free
\n

\nSystem Requirements:\n

\n
• Skype Client
\n
• Working Java 1.6.0 or better runtime
\n
• mjsip/mjua 1.6 http://www.mjsip.org/ - Use those included with SippySkype as some bugs have been fixed.
\n
• Skype4Java 1.0 https://developer.skype.com/wiki/Java_API - Unmodified
\n
• SIP/VOIP adapter such as a spa-3102 to make and receive Skype calls or register with a provider or Asterisk.
\n
• Should work where Skype4Java works (windows/linux/osx). (I'm using it on Windows XP)
