Yes, I meant the "human" person could do it. Anyway common softphones don't allow a REGISTER option (except Twinkle as I know), so just forget my suggestion. :) > > If you are in a escenary with easy connection lost then is user task to > > set the REGISTER period shorter. > > no sip specification today mandates or even recommends setting register > period short if there is possibility for temporary loss of connectivity. > dropping of registration if contact does not respond would thus cause > problems. Yes, but there are problems too if a registered user has killed him softphone or PC without letting it sending the un-REGISTER. In that cases other user calling to him receive an infinite "Trying", while with my suggestion of un-register, callers would see "not found". I don't know which issue is worse, but I'm sure that too many times a SIP device "dissapears" without sending a un-REGISTER. There could be two options: modparam("nathelper", "unregister_not_ping", 1) - 1: Enabled - 0: Dissabled. modparam("nathelper", "unregister_not_ping_time", 60) - Time after a not ping responding user should be un-registered. PD: Do you think I could report this as a wish in the tracker? or are you sure is really a bad idea?
