Well, 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.
Check out the features:
- 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
- Call Skype Users using speed dial or use Skype out.
- SIP to Skype authentication/denial mappings via SIP caller ID and IP blocks - 1.1 or higher
- Skype to SIP authentication/denial mappings via incoming Skype User ID - 1.1 or higher
- Support RFC2833 touchtone decoding (DTMF) - 2.0beta or higher
- Could be used as an endpoint with Asterisk
- Auto play pre-recorded file(s) to SIP callers - 2.0beta or higher
- Incoming SIP Pin number authentication and dialing - 2.0beta or higher
- Open Source - You can modify/fix it if you like.
- It's free
- Skype Client
- Working Java 1.6.0 or better runtime
- mjsip/mjua 1.6 http://www.mjsip.org/ - Use those included with SippySkype as some bugs have been fixed.
- Skype4Java 1.0 https://developer.skype.com/wiki/Java_API - Unmodified
- SIP/VOIP adapter such as a spa-3102 to make and receive Skype calls or register with a provider or Asterisk.
- Should work where Skype4Java works (windows/linux/osx). (I'm using it on Windows XP)
