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.

How i wish it was true. But it is not. I test MS intergrationi 2 weeks already and MS never respons about that they expect.

Moreover, there is no example in their documentation how INVITE (to MS) with record-route headers should looks like.

The only response  I get from them is 200 OK for OPTIONS. 

Also I got outbound calls from MS working.

Can you send your masked INVITE if possible ?

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.

 

Cheers,

 

Henning

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 those, I AFAIR you can set dynamically with record_route_preset() / record_route_advertised_address()

There’s no need for FQDNs in Via headers for MS. IPs work just fine!

You need FQDNs only in Route/Record-Route headers.

Comrade :)

 

Thanks for the advices! I will try them.

 

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.

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. Or may be I'm wrong and your specifics do require it.

Good luck comrade.

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 ?

Most common way is by using `advertise`  in the `listen` directive.

Hi guys,

 

It sounds simple but I can not get  domain name in VIA header (INVITE) instead of IP address.

 

It is just 

 

FS ---INVITE --> Kamailio --INVITE--> endpoint

 

Kamailio gets INVITE, and adds one more VIA with it's IP address. How to get domain name instead ?

 

Please advice.
