[http://www.rsdevs.com/ RSdevs] has created a gateway (PSGw) to let Skype communicate over SIP or H323 to communicate with other systems like an Asterisk PBX.
In other words; An unified interface to several VoIP networks (SIP/H.323/Skype) in a single application.

'''Here's how it works:'''
# User makes a SIP URI call (using SIP phone or softphone) to a domain where the PSGW software is located. For this example, suppose I have it running on my domain: tmcnet.com. Thus, you can simply SIP dial <username>@tmcnet.com
# The call is routed to the tmcnet.com firewall or SIP proxy with port 5060 mapped to a PC running Skype and the PSGW software.
# The PSGW takes the SIP call, strips off “<username>” from <username>@tmcnet.com and then initiates a Skype call to Skype user “<username>”. (Thus, you simple need to pre-pend the Skype username you wish to call to the domain.)
# The PSGW then “bridges” the audio from the Skype leg of the call with the SIP leg of the call.

That's it! You've just made a SIP-to-Skype call. Skype's Great Wall of VoIP has just been breached! Granted, it is a bit of a "kludge" requiring a host PC running Skype & PSGW, but cool stuff nevertheless, eh?
