al286320 created an issue (kamailio/kamailio#4298)

Hi all,

I'm new to Kamailio, and maybe this is a silly question.

I’ve set up Kamailio as a SIP proxy with two Asterisk servers acting as media services.

This is my configuration for the dispatcher module:

loadmodule "dispatcher.so"

modparam("dispatcher", "db_url", DBURL)
modparam("dispatcher", "table_name", "dispatcher")
modparam("dispatcher", "flags", 2)
modparam("dispatcher", "ds_ping_interval", 20)
modparam("dispatcher", "ds_ping_method", "OPTIONS")
modparam("dispatcher", "ds_probing_threshold", 5)
modparam("dispatcher", "ds_inactive_threshold", 5)
modparam("dispatcher", "ds_ping_latency_stats", 1)
modparam("dispatcher", "ds_probing_mode", 1)
modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=403;code=488;class=3")
modparam("dispatcher", "ds_ping_from", SIPCALL)

I can see the SIP OPTIONS requests going from Kamailio to Asterisk and receiving 200 OK responses.

However, the dispatcher is still setting the IP (Inactive Probing) flag on the servers:

kamcmd dispatcher.list
{
	NRSETS: 1
	RECORDS: {
		SET: {
			ID: 1
			TARGETS: {
				DEST: {
					URI: sip:172.16.254.21:5060
					FLAGS: IP
					PRIORITY: 0
					LATENCY: {
						AVG: 0
						STD: 0
						EST: 0
						MAX: 0
						TIMEOUT: 183
					}
				}
				DEST: {
					URI: sip:172.16.254.20:5060
					FLAGS: IP
					PRIORITY: 0
					LATENCY: {
						AVG: 0
						STD: 0
						EST: 0
						MAX: 0
						TIMEOUT: 183
					}
				}
			}
		}
	}
}

So when I try to use ds_select_dst("1", "4"), it always fails.

Did I miss something in my configuration?

Thanks!
