Re: Mismatch ClientTransactions from multiple INVITEs

Kalman,

That zip is pretty old. If you are working with the proxy,  sorry its 
badly out of date. I will attempt to catch up with the proxy and update 
it to the current jain-sip version -- its on my todo list but I cant say 
when. If you can  pitch in and help with that, it can happen sooner than 
I can manage on my own.

If you are building your own application on top of jain-sip, I strongly 
suggest getting the latest source (i.e. jain-sip-1.2)  from the nist cvs 
repository (see jain-sip.dev.java.net for cvs details). Although the TCK 
is still to be done, it fixes some bugs with the older version and 
includes some important missing functionality (i.e. Jain-SIP-1.2).

In particular the implementation includes a per transaction semaphore 
for the transaction state machine that the old version did not have. 
This may well be the issue you are having in a multithreaded 
environment. Do download and try it out.  If you still have such 
problems with the latest version from cvs, however, it would be great if 
you can provide me with a small test case that I can debug.

Regards,

Ranga
