Hi Benny ? I actully use the TCP to test the bulk call. I cannot make sure my scenario is the same as you list. When the system uses TCP to register to sip server, I think TCP connection is always establishe to server. so I cannot realize the description as below: before TCP connection is established, the 200/OK retransmission arrives If I dont disable the assertion, and I have to use the TCP transation. Can you give me a suggestion to do the other work around to avoid the situaiton?until the next release ? Thanks your reply. ?

I use bulk machine to test SIP basic call. and soemtime the app show the log as below:? .../src/pjsip/sip_transport.c:628: pjsip_transport_send: Assertion `!"Invalid operation step!"' failed. I don't how it happen, but it will cause cannot make a next call. I check the code has error handling in the next line of pj_assert. Can I mark this pj_assert? ? No, it's not a good idea to disable that assertion. This is a bug, and I've added a ticket for this: http://trac.pjsip.org/repos/ticket/1011. Is the scenario explained in the ticket the same as yours? If so, the work around is to not use TCP for now until the ticket is fixed.
