Hi Joe,

Well, of course there is the Openzoep SIP stack :)

No but seriously, I do understand what you are saying: we looked at a 
lot of SIP stacks too (mostly the ones in 
http://www.voip-info.org/wiki/view/Open+Source+VOIP+Software), but they 
often go into directions you describe or are diffecult to use because 
they are embedded in a larger application (and/or use other libraries 
from that application - but this could be handled, if given time.)

One library I liked very much because it was small and well designed is 


The author is very friendly and happy to discuss features, enhancements etc.

And of course there are commercial SIP stacks (either available as 
library or not), of which I cannot say anything, since I did not have 
the opportunity to try them out.

Regards, Dirk
