[SR-Users] Dispatcher sets IP flag on servers even though SIP OPTIONS receive 200 OK

Hi there,

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!

Regards, Pablo.
