    Hi all, I'm a newbie.
    In my company (Korea) there is a opensips server for VoIP.
    and the session call between China side and Korea side always drop the call after exactly 30 minutes,
    but the session call between Korea and Korea there is no session expire phenomenon whatever after 10 hours.
    I really want to know the reason why the session will expire after 30 minutes.
    Please… tell me

    Hi,

    When you say the call drops - is any of the parties sending a BYE ?

    Maybe you are using different GWs for those 2 types of calls and each GW has a different SST (SIP Session Timer) value set…..

    Regards,
    Bogdan
