I am not sure what you exactly try to achieve, but for the record-route parameter, I can provide two options for you.

If you are not satisfied with the second record-route, you might remove (remove_hf();) "Record-Route" header before adding a new one via 'record_route_preset'.</div>

But I think it is like a workaround solution, for better way you can check whether you used "record_route();" or not before/after using ''record_route_preset''<br>

<div>Yes, I follow that post to configure it. But I don´t know where could be the problem and change Record-Route, because, in the post say, only I have to change it when I call from kamailio to Teams, so outgoing calls, right? With record-route-preset... I'm

You only have to load the module and set:<br>

Also you can enable or disable using RPC commands:

<p>Hello,</p>
<p>it seems that the ACK comes in, but my guess is that the R-URI is not properly set. From the logs it looks like same value as for To header URI, while it should be the address in Contact header of 200ok for INVITE.</p>
<p>Load the sipdump module and that will save all the sip traffic in a text file, making it easier to see what comes/goes on both directions, no matter is over tls or not. If you use kamailio devel version (master branch), then sipdump module can also store
traffic in pcap file (tls traffic saved as udp for simplicity, but it is easy to spot from headers or meta data extra header).</p>
<p>You can send the sipdump file here for investigation, so we can see if some headers or r-uri are not correct.</p>
<p>Cheers,<br>
Daniel<br>

<p>Hello,</p>
<p>run with debug=3 in kamailio.cfg and see if the ACK comes to Kamailio, if yes, then some routing issue in kamailio.cfg. If does not come, you will have to check the headers to see if MS Teams expects something else there, typically is about Record-Route
domains...</p>
