I don't know. Try to write the domain directly and not an alias:

record_route_preset("yourdomain.com:5061;transport=tls", "your_ip:5060");

Yes, this is I do:

Have I do any more? Why mu record-route is different yours?

Thanks

You have to use record_route_preset when the message is sent from Kamailio to Teams

if (from_uri =~ ".*microsoft.com") {

Thanks Pepelux..

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 wrong?

Thanks

When the call is from Teams (src_ip != "IP ASTERISK"), incoming calls, I send the call to 1005 extension. Is here where I have to make the change? Or where?

Thanks

Hi

Kamailio doesn't receive any ACK from Teams. I think the problem is the '200 Ok' that you send to Teams is not what he expected. Maybe this is wrong:
Record-Route: <sip:FQNDIP;r2=on;lr>
Record-Route: <sip:FQNDIP:5061;transport=tls;r2=on;lr>

Try to put the registered domain (FQNDDNS) and not de IP address

You only have to load the module and set:
modparam("sipdump", "enable", 1)

Also you can enable or disable using RPC commands:
kamcmd sipdump.enable
kamcmd sipdump.enable 1
kamcmd sipdump.enable 0

Hello,

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.

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).

You can send the sipdump file here for investigation, so we can see if some headers or r-uri are not correct.

Cheers,
Daniel

Hello,

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...
