[SR-Users] Re: help on how to get ACK

This is the contact in your 300: sip:service@10.20.0.3:5060?P-Asserted-Identity=%2216001%22%3Csip%3A16001%3Bverstat%3DTN-Validation-Passed%4010.20.0.2%3A5060%3E This is the URI in your ACK: sip:1@10.20.20.1:5060 It looks like you're using SIPp which is a pain this way. Rather than coding the URI into the ACK of your SIPp scenario, add rss="true" to the recv line for your 300, and then use [next_url] in the template for your ACK mesasge. Here is an example: https://github.com/whosgonna/kamailio_http_async/blob/reply300/sipp/uac_exp… Kaufman Senior Voice Engineer E: bkaufman(a)bcmone.com SIP.US Client Support: 800.566.9810 | SIPTRUNK Client Support: 800.250.6510 | Flowroute Client Support: 855.356.9768 [img]<https://www.sip.us/> [img]<https://www.siptrunk.com/> [img]<https://www.flowroute.com/> ________________________________ From: Sergio Charrua &lt;sergio.charrua(a)voip.pt&gt; Sent: Monday, December 23, 2024 4:14 PM To: Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt; Cc: Alexis Fidalgo &lt;alzrck(a)gmail.com&gt;om>; Ben Kaufman &lt;bkaufman(a)bcmone.com&gt; Subject: Re: [SR-Users] Re: help on how to get ACK CAUTION: This email originated from outside the organization.

After all the real useful and interesting thread on that topic what helped me, im facing a problem i cant deal with and need a hint at least. Scenario INVITE -> Kamailio on request_route ... if(is_method("INVITE")){ t_newtran(); http_async_query("http://nuc:8080", "HTTP_REPLY"); } … Kamailio -> 100 - Trying then route[HTTP_REPLY] { if ($http_ok) { xlog("L_INFO", "route[HTTP_REPLY]: status $http_rs\n"); xlog("L_INFO", "route[HTTP_REPLY]: body $http_rb\n"); t_reply(302,"Redirect"); } else { xlog("L_INFO", "route[HTTP_REPLY]: error $http_err)\n"); } } Kamailio -> 302 Redirect ACK -> Kamailio This last ACK, how can i read it and use it to terminate the transaction? because Kamailio keeps transmitting the 302 message 3 more times until the transaction is finished by a timer 42(44) DEBUG: tm [t_reply.c:1723]: t_retransmit_reply(): reply retransmitted. buf=0x7f4c44f9d680: SIP/2.0 3..., shmem=0x7f4c3fce7900: SIP/2.0 3 42(44) DEBUG: tm [t_reply.c:1723]: t_retransmit_reply(): reply retransmitted. buf=0x7f4c44f9d680: SIP/2.0 3..., shmem=0x7f4c3fce7900: SIP/2.0 3 42(44) DEBUG: tm [t_reply.c:1723]: t_retransmit_reply(): reply retransmitted. buf=0x7f4c44f9d680: SIP/2.0 3..., shmem=0x7f4c3fce7900: SIP/2.0 3 42(44) DEBUG: tm [timer.c:642]: wait_handler(): finished transaction: 0x7f4c3fcd35a0 (p:0x7f4c3fad85d0/n:0x7f4c3fad85d0) 42(44) DEBUG: tm [h_table.c:133]: free_cell_helper(): freeing transaction 0x7f4c3fcd35a0 from timer.c:651 in request_route i have if(is_method("ACK")){ if(!t_check_trans()){ t_release(); } exit; } __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions -- sr-users@lists.kamailio.org<mailto:sr-users@lists.kamailio.org> To unsubscribe send an email to sr-users-leave@lists.kamailio.org<mailto:sr-users-leave@lists.kamailio.org> Important: keep the mailing list in the recipients, do not reply only to the sender! __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions -- sr-users@lists.kamailio.org<mailto:sr-users@lists.kamailio.org> To unsubscribe send an email to sr-users-leave@lists.kamailio.org<mailto:sr-users-leave@lists.kamailio.org> Important: keep the mailing list in the recipients, do not reply only to the sender!
