Hello Thomas,
Please find the explanation of your quries
*1)* "*pjsua_acc_info::status*" gives the last status code received by the
user-agent for the *REGISTER* request (REGISTER request may be for
registration or un-registration) status code 200 means Success for the
REGISTER rrequest.
*2) * According to SIP specification difference between registration and
un-registration request is expire time send by the user-agent if expire
time is >0 then request is for registration otherwise for un-registration.
Expires header in the registration request indicate registration refresh
interval
*3) Sipgates web-site gives the status name of the user-agent currently
register with the sipgate. you can give name of the pjsua user-agent by just
changing few lines of code *
*
*
app_cfg.user_agent = pj_str("<*THOMAS USER AGENT*>");
Thanks and Regards
Sushil Kumar
