Thanks for the answer Sergiu, but this shoud not be static domain name. I need to have different domains in Via for different calls. Is it possible ? On Fri, 24 Apr 2020 at 21:37, Sergiu Pojoga <pojogas(a)gmail.com> wrote:

Yuriy, The 'advertise' parameter doesn't support vars. ( https://github.com/kamailio/kamailio/issues/2137) As an alternative, you could use a combination of xavps and corex module function via_use_xavp_fields() -- see: https://www.kamailio.org/wiki/cookbooks/5.3.x/core#xavp_via_fields If you're building this for what I think you are, most likely you think you need this - but you actually don't.

Well, you just posted an example of a valid INVITE. Nothing wrong with it. Have you tried the `advertise` FQDN that was previously suggested? I understand it would be static domain, but in most cases - it's all you need, unless you're building a multi-tenant solution. If it's the later option - then try xavp_via_fields, but I can tell you upfront if you do that - then you must be doing something conceptually wrong (I'll leave the details to my know-how and let you figure out the rest) On Sat, Apr 25, 2020 at 1:09 PM Yuriy Nasida <ynasida(a)gmail.com> wrote:

Hello, as mentioned already in discussions of this topic, there is no need to add a domain name in VIA headers. There is all information that is needed to have a basic setup working in the respective post on my blog. Usually Microsoft will send you a reply if something is not how they expect it to be.

Guys, I really happy that you send INVITES to MS with record_route_preset and MS does not ignore. But I really not sure how your INVITE looks. Can you please send one here ? That can help a lot. Also please look at INVITE we send (MS ignores this).

And yes, that is for inbound calls to MS teams. We just got outbound calls working by the way (had to do a lot of kamailio tweaks honestly). As for inbound calls to MS - I just looking at their docs (picute attached). Looks like MS expect domain name in VIA. I have all other sip headers like they want, but MS still ignore our INVITEs. That is why I think how to change VIA. If you have example of INVITE to MS teams that is working - that can help a lot.

Well. We switched back to 'lets encrypt' certificate and MS started responding. Finally :) It's so mystical how MS check certificates by the way. Inboiund TLS session was set up fine and there were no errors in tcpdump. But they unexpectedly terminate the TLS session at the time of receipt of INVITE. In the meantime outbound TLS session worked grear. We will have to think how to change CA list for cert that is not working. Thanks for your help, guys.
