http_event have errors with exec_avp

Hi there! we have an issue, and it's similar to reported in this thread: http://sip-router.1086192.n5.nabble.com/exec-warning-td165448.html We use kamailio 5.0.6. When we call route from http_event by url reguest (code is below) event_route[xhttp:request] { set_reply_close(); set_reply_no_connect(); if ($(hu{url.path}) ==”update”) { route(DO_SMTH); xhttp_reply("200", "OK”, "", ""); } route[DO_SMTH] { exec_avp(“/usr/bin/who”,”$avp(s:user_)”); } we got errors exec like these: Mar 1 10:51:05 test kamailio[21035]: WARNING: exec [exec_hf.c:464]: append_fixed_vars(): uri not parsed Mar 1 10:51:05 test kamailio[21035]: WARNING: exec [exec_hf.c:482]: append_fixed_vars(): orig URI not parsed Mar 1 10:51:05 test kamailio[21035]: ERROR: exec [../../core/char_msg_val.h:51]: char_msg_val(): can't calculate char_value due to a parsing error Mar 1 10:51:05 test kamailio[21035]: WARNING: exec [exec_hf.c:492]: append_fixed_vars(): no tid can be determined Mar 1 10:51:05 test kamailio[21035]: ERROR: exec [exec_hf.c:504]: append_fixed_vars(): no to-tag But when we call route(DO_SMTH) from request_route - there are no such errors We think that it is something related to the nature of event_routes, anything can be done with this? Should I create an issue on github? thanks for insights and ideas

Re: [SR-Users] How to Absorb First Leg Re-Invites when no Response from Second Leg Invites

Yes, retransmissions of initial INVITE from Carrier. Makes perfect sense, I understand now. Thanks Gentlemen! JR Reinvites are in-dialog requests; they would only be sent within the context of an established dialog (2xx response, end-to-end ACK, the whole works). Perhaps what you are referring to is not reinvites but retransmissions of the initial INVITE? If so, have a look at this option: https://kamailio.org/docs/modules/5.2.x/modules/tm.html#tm.p.cancel_b_method in concert with something like this: failure_route[...] { if(t_is_canceled()) exit; # The scenario you're after. if(t_branch_timeout()) { t_reply("503", "Service Unavailable"); exit; } } -- Alex

Is there a option to execute multiple command via JSONRPC or XMLRPC

Hi, I am looking for a option to execute multiple command via JSONRPCS or XMLRPC. To avoid multiple tCP connections . eg: I have multiple kamailio load balancer server running, need to update the dispatcher record in a single command. Regards, Vimalesh S

How to Absorb First Leg Re-Invites when no Response from Second Leg Invites
by JR Richardson 02 Mar '19

02 Mar '19

Hi All, My mind is not right on this one, need a pointer. Here is the simple scenario: Carrier><kamailio proxy><end device The end device is a static IP, the proxy dips database and knows where to send numbers destined for the end device, but if there is no response from the end device (it's off-line), how do I time-out the transaction and send a 503 'Service Unavailable' back to the first leg for the carrier to stop re-invites? I assume I need a new [FAIL_TWO] route that handles this event. Thanks. JR -- JR Richardson Engineering for the Masses Chasing the Azeotrope
