Hi, tried to investigate problem by myself with no luck.

On the very first SIP INVITE server sends Trying & OK messages
but client side stack 'putting pending' messages and raise
timeout event. Here is debug messages:

...

putting pending SIP/2.0 100 Trying

...

putting pending SIP/2.0 200 OK

....


Does anybody knows what is the cause of this ?

This happens only on very first request, all other
requests processes normally.

Saw the comment about dual processors - tried on few
different with one processor - the same effect.

Both client and serevr stack using the same
1.1 version of the stack. Sources of the both sides
is under my control. Moving into 1.2 is not desired.

Thanks
