The network trace of the SIP messages would help to figure out the
message flow and, maybe, to get the reason why the transaction is no
longer active. If you have openser and sems on same system then you
should watch the loopback interface, too:
ngrep -d lo port 5060

I used the config u sent me now am getting this error in my log.
am using SEMS 0.9.0 and I have no idea what these errors mean

could not send response.
Did you get around this problem? The log messages say that sems tries
to send a reply to a transaction that does not exists in openser. This
can be due late reply (the transaction expired) bad parameters sent
over fifo from sems to openser.
Would help a network trace for such situation (using ngrep or
ethereal). Also, you can increase the debug level in openser and sems,
to get more messages.
