Hello,

There is no such mechanism - as said, subscribing to a user's presentity (and the whole presence stuff) is completely independent from the registration mechanism. There is no need to register in order to have presence working.

The subscriptions are time based (they have an expire, exactly like registration), so , even if the UA crashed, the subscription will timeout after some time (exactly like the registration, but independent and maybe with different timeout value). So, the crashed UA will go "offline" at some point (because of the subscribe expire) - there is no need for a parallel mechanism (the registration expire).

Yes, this is correct.

I would like to know if there is a mechanism to notify all the subscribed users when an account expires.

Thank you,

    Hello,

    You are mentioning 2 different things here : (1) presence for
    notifications and (2) registration status of the user.

    Presence and registration are not related at all (unless using the
    pua_usrloc module).

    The closest I can understand is: you have presence between UAs and
    one UA crashes -> the other UAs are still seeing it online (and
    not offline) - is this correct ?

    Hello,

    I have a presence enabled Opensips server and am facing the
    following issue.

    My SIP client sometimes stops in an unfriendly manner (crashes
    etc..) and the account remains active on the registrar side
    (until the registration period expires, of course).

    I would like to notify all the users which are subscribed to this
    user when the account expired.

    Any help would be appreciated.

    Thank you,
    Bogdan Chifor.
