What is SippySkype?
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/Adapter/Converter. It has a codec converter to convert SIP PCMU RTP audio to compatible Skype PCM audio and Skype PCM audio to SIP PCMU RTP audio. It performs SIP signaling and Skype call handling with your SIP adapter, Asterisk Server or SIP VOIP provider.

SippySkype Features:

• Call Skype Users using speed dial or use Skype out.
• Skype Callers can be directed to the SIP address of your choice.
• SIP to Skype authentication/denial mappings via SIP caller ID and IP blocks
• Skype to SIP authentication/denial mappings via incoming Skype User ID
• Supports RFC2833 touchtone decoding/encoding (DTMF)
• Connect Asterisk to Skype Users
• Auto play pre-recorded file(s) to SIP and Skype callers
• Incoming SIP Pin number authentication and dialing
• Open Source - You can modify/fix it if you like.
• It's free - Don't pay anything to anyone to use this software.

System requirements:

• Skype Client
