Hi Experts.
I come across that for VoLTE register messages i-cscf is not populating it’s ip address with via header. When I check the register messages from icscf to scscf top most via is not icscf but it is asbc (pcscf).
Is it normal?

What exact your flow?
Is it 401 unauthorized missing after 1st register message?
Or 200 ok missing?

None of them is missing.for register message from icscf to scscf I missed the top via header which should be icscf address but I did not see it.
Now it is ok, thanks!
