Re: [SR-Users] Proxy configuration that exit dialog afer INVITE -> OK
Hello, Thank you for response. In my case, my client wants to have this behavior, its not my choice; that is the server only proxy in the initial transaction, and the UA continues in direct all the following dialog. I comment out the record_route() functions and I see in wireshark that I obtain requested behavior, hope this have no side effects. Next, I would like to make a stateless proxy, that still manages registrations and routes the messages, to compare with no record route.

Re: [SR-Users] Proxy configuration that exit dialog afer INVITE -> OK
Hi, Here's an example kamailio.cfg that uses record_route so in-dialog requests will go through the Kamailio proxy: https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg There are many other example cfg files: https://github.com/kamailio/kamailio/tree/master/misc/examples Any server that wants to see the in-dialog messages needs to add itself to the record route list when receiving the initial INVITE for example. If a server is not in the list of record routes, then in-dialog requests will not be sent to the server. Headers that are most important in terms of routing are R-URI, Route, Record-Route, Contact, Via. Via header is for routing responses, while Record-Route is for in-dialog requests. I've put a few tips and some resources here about starting with Kamailio, which hopefully may help you a bit: http://tao-communications-ltd.simplesite.com/447576389 Cheers, Yufei >* Message: 7 *>* Date: Thu, 5 Nov 2020 12:26:16 +0200 *>* From: "Adrian Tabacioiu" https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users>> *>* To: sr-users at lists.kamailio.org <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users> *>* Subject: [SR-Users] Proxy configuration that exit dialog afer INVITE *>* -> OK *>* Message-ID: <7449102a9f3dbe38b6dba753d1cffcd8.squirrel at mail.c-s.ro <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users>> *>* Content-Type: text/plain;charset=iso-8859-1 *>>>* Hello all, *>>* Am I new in the usage of kamailio, sorry if I ask somehow something simple *>* or terribly wrong . *>>* I need to test a configuration of Kamailio which exit the dialog between *>* UA after the first OK (that means it will not receive the following ACK, *>* BYE). *>>* I understand that in theory this is possible in two configuration types: *>* - no Record Route header *>* - or stateless proxy *>>* First question: *>* Am I correct with the choices above? *>* Can I find example configuration for this two modes ? *>>* Question 2: *>* two or more proxy should be inter-connected, removing the Record Route *>* header would interfere with proxy routing ?

[SR-Users] Proxy configuration that exit dialog afer INVITE -> OK
Hello all, Am I new in the usage of kamailio, sorry if I ask somehow something simple or terribly wrong . I need to test a configuration of Kamailio which exit the dialog between UA after the first OK (that means it will not receive the following ACK, BYE). I understand that in theory this is possible in two configuration types: - no Record Route header - or stateless proxy First question: Am I correct with the choices above? Can I find example configuration for this two modes ? Question 2: two or more proxy should be inter-connected, removing the Record Route header would interfere with proxy routing ? (should not the "Via" information be sufficient?) Thank you in advance for help.
