No, it is completely independent and is not based on any existing 
software. It has been written by me from scratch in python. 
Performance-wise it comparable with Vovida one but has not been 
optimised in any way so that there must be some room for improvement. 
Unlike Vovida one, which is quite a mess inside, I've tried to make it 
layered as much as possible, so that it should be very easy to code some 
call control logic without dirtying hands with SIP protocol internals. I 
think that my goal has been reached, since I've already easily created 
several absolutely different applications:

o "conventional" b2bua.

o sip callback b2bua that doesn't use REFER, BYE/also or any other 
non-mandatory SIP method or hack for its work, just plain INVITEs and 
re-INVITEs, which should be supported by any SIP device.

o MWI agent, application which can on demand turn on or off MWI (message 
waiting indicators) in lot of SIP UAs registered in a proxy during a 
small amount of time.

If you don't mind signing NDA I can send you a code, so that you can see 
if it is worth waiting for the release. I would like to have NDA since I 
have not decided on the license yet (most likely GPL but some 
free-for-non-commercial-use is also an option under consideration). In 
spite of the recent copyright turmoil with nathelper/mediaproxy I would 
like to ensure that my interests are protected as much as possible.
