Deal all ? 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? ? The description of the pj_assert from assert.h is list as below: /** ?* @hideinitializer ?* Check during debug build that an expression is true. If the expression ?* computes to false during run-time, then the program will stop at the ?* offending statements. ?* For release build, this macro will not do anything. ?* ?* @param expr???? The expression to be evaluated. ?*/ #ifndef pj_assert #?? define pj_assert(expr)?? assert(expr) #endif ? ?
