Hi! I have a Kamailio 1.5.2 handling 3XX messages. The commands below are executed in a failure route. If the first contact is not reachable or even a negative answer is received, the algorithm will call a second failure route, executing the 't_next_contacts'. Following this logic, the server will try several endpoints. The first 200 OK received from one this endpoints will establish the call. If all the contacts are tried, the server will finish the session with sending an error to the source. get_redirects("15:15","Redirect"); if(!t_load_contacts()) { t_reply("500", "Server Internal Error - Cannot load contacts"); exit; }; if(!t_next_contacts()) t_reply("404", "Not found"); else t_relay(); Ok... I found just one problem. If the 3XX message brings 5 different contacts, (all them with different q value), Kamailio just try 4 of them. Contact: sip:20182#556250982222@aaa.aaa.aaa.aaa;q=0.015, sip:3441#556250982222@bbb.bbb.bbb.bbb;q=0.014, sip:3441#556250982222@ccc.ccc.ccc.ccc;q=0.013, sip:50014#556250982222@ddd.ddd.ddd.ddd;q=0.012, sip:777#556250982222@eee.eee.eee.eee;q=0.011 After the 300 message, the server sends a invite to the first contact. Seconds later, analysing the debug screen, I see: DBG:tm:t_next_contacts: next contact is <sip:3441#556250982222@bbb.bbb.bbb.bbb The INVITEs are sent to this IP. After some seconds the server calls the third contact: DBG:tm:t_next_contacts: next contact is <sip:3441#556250982222@ccc.ccc.ccc.ccc And so on until this, the last contact: DBG:tm:t_next_contacts: next contact is <sip:777#556250982222@eee.eee.eee.eee ERROR:core:add_avp: 0 ID or NULL NAME AVP ERROR:tm:t_next_contacts: setting of fr_inv_timer_avp failed The proxy sent INVITEs for all them, except the last one because this failure. The function 't_next_contact' returns an error value. Somebody has a hint about this?
