My client send sip message via udp,so I think the WRONG_CALL_STATE may
product by some package send failure.The most important problem is
client recive "503 System Busy".When I trace the code,I find it is
product in src/mod/endpoints/mod_sofia/sofia.c,and the condition is: if
(switch_queue_size(mod_sofia_globals.msg_queue) > (unsigned
int)critical) { nua_respond(nh, 503, "System Busy",

Why will product these?
