Hi All, I have put pjsip 1.4.0 on my target device, but I sometimes encounter the assertion for "invalid operation step" in sip_transport.c. It looks like someone tdata is pending, but why we need do assertion here ? Can I remove this assertion ? Could someone give me some adivce ? Thanks a lot. -- Best Regards, Alex Liu foxconn mail : alex.ch.liu at ambit.com.tw private mail : jahowliu at gmail.com msn : jahowliu at yahoo.com.tw -- Best Regards, Alex Liu foxconn mail : alex.ch.liu at ambit.com.tw private mail : jahowliu at gmail.com msn : jahowliu at yahoo.com.tw -------------- next part -------------- An HTML attachment was scrubbed...
