What version of Asterisk are you using? I am also using Asterisk for routing calls to Home Assistant but my INVITE messages do have a "via" header. Any chance you could get a packet capture or something and look at what your SIP messages look like?

Asterisk 20.3.0 self-backported from sid to buster, client: latest linphone from f-droid

oh, sorry, looks like it was some misconfiguration on my side, I rewrote config from scratch and now it works fine!
