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

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

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 ?

Тема: Re: [SR-Users] how to use get my domain name in VIA header (INVITE) instead of IP address.

 

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.
