Hello I'm trying to implement following scenario: - remote GW is Active (receives calls) and not Probed (no SIP Options are being sent); - in case if remote GW failes, it starts to be Probed and become Inactive ("ds_probing_threshold" does this); - when remote GW returns it remains in Probed and Inactive state for a while; - after probing for some amount of time (or a number of successful responses) it become Active and not Pobed (it can be achieved with "ds_inactive_threshold"); The issue I'm facing is that "ds_inactive_threshold" will bring GW back only after the number of successful responses that can't be provided using "ds_probing_mode" with value 2. It stops to produce SIP Options by successful reply before threshold of successful replies is reached. In case of "ds_probing_mode" with value 3 I haven't found a way to stop Probing when GW transits to state Active. Is there a way to make GW Active after it was Inactive and was successfully probed for arbitrary number of times? Some valuable information: Kamailio: v 4.4.2 ... modparam("dispatcher", "ds_ping_interval", 3) modparam("dispatcher", "ds_probing_threshold", 3) modparam("dispatcher", "ds_inactive_threshold", 60) modparam("dispatcher", "ds_probing_mode", 2) ... If I missed any information please tell me. With best regards Ivan
