Hello,
I'm experiencing an issue with the dispatcher module where setting a destination state to "IX" (Inactive + No probing) using dispatcher.set_duid_state doesn't stop OPTIONS probing.
Configuration: modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_interval", 60)
Steps: - Destination is being probed normally - Execute: kamcmd dispatcher.set_duid_state ix 11 ma5q - kamcmd dispatcher.list shows FLAGS: "IX" - SIP OPTIONS continue being sent to this destination
I was expecting that marking the destination with the X flag would stop the probing. Is this incorrect behavior or do I need to use other ds_probing_mode value?
I'm using kamailio version 5.8.4
Thanks, Regards, Tiago Serra

docs say that if ds_probing_mode = 1, all gateways are pinged:

i think yoy should use probing mode 2 instead: " inactive mode and only if Probing is set".

Thanks for your answers, I understood wrong the documentation and thought that even with ds_probing_mode = 1, I could skip some entries setting them with 'X'.
I changed to ds_probing_mode = 3, and now it works as I wanted, it will stop probing when I change the state to 'X' and it will start again when I change to 'P'.
Thanks! Tiago
