Miha, First, do you need to use "mtsbc.test.com:5060" in the first record_route_preset() param? Can you use the IP address of your proxy instead? FQDNs are legal of course, but outside of MS Teams' implementation, they're rarely required. It's just another thing to go wrong. Especially while testing.
The ACK to the 200 OK is a sequential (in-dialog) request. It's not part of the original INVITE transaction. Your script will have a section like if (has_totag()) { if (loose_route()) { t_relay(); } } for sequential requests through a loose-routing proxy. This is very oversimplified and yours will have more. In this section, however, is where you'll process the ACK because it has a to-tag (line 293) and a route header (line 298) so the conditions match. Use xlogs or the debug tool of your choice to diagnose what's happening in this section with the ACK. In my scripts, I use global flag 0 to indicate when I want logging. So, I might have something like this: if (has_totag()) { if (is_gflag(0)) xlog("L_NOTICE", " ...in-dialog $rm request\n"); # ...do all the things...maybe more logging like the line above... - Jeff On Tue, Jun 1, 2021 at 4:57 AM Miha via Users <users@lists.opensips.org> wrote: > Hello > > > I have an issue and I am unable to find out what is wrong.
