DUAL Softswitch has been the switching and billing engine behind our own VoIP calling service (DUAL Talk) since 2003.

It is designed and tuned specifically to run on Windows Server and was written completely in-house; right down to the H.323 and SIP protocol stacks.

We are making the final preparations to launch DUAL Softswitch as a commercial product, and expect it to be in general release in the next few months.
