Running compiled Kamailio 5.8.1 (previously 5.8.0) on Debian 12 64-bit We're seeing an issue with UDP endpoints (this issue does not happen with TCP and TLS) where usrloc will not send OPTIONS packet keepalives. Here are all of our usrloc parameters: modparam("usrloc", "db_mode", 0) modparam("usrloc", "ka_domain", "SIPDOMAIN") #-- SIPDOMAIN is a fqdn modparam("usrloc", "ka_from", "sip:proxy-ping@SIPDOMAIN") modparam("usrloc", "ka_mode", 1) modparam("usrloc", "timer_interval", 20) #-- How often to qualify endpoints and clean mem tables? modparam("usrloc", "timer_procs", 4) modparam("usrloc", "ka_randomize", 10) modparam("usrloc", "use_domain", 0) modparam("usrloc", "server_id_filter", 1) modparam("usrloc", "ka_filter", 0) modparam("usrloc", "ka_timeout", 60) #-- How quickly to expire a contact if it does not reply to keepalive? modparam("usrloc", "matching_mode", 0) modparam("usrloc", "handle_lost_tcp", 1) modparam("usrloc", "close_expired_tcp", 1) modparam("usrloc", "desc_time_order", 1) modparam("usrloc", "hash_size", 14) It seems usrloc is not actually using timer_interval at all for UDP devices. However, it does seem to be sending OPTIONS every 20 seconds on TCP/TLS. (this is confirmed via packet capture on a SIP phone). -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3844 You are receiving this because you are subscribed to this thread.
