Sorry for the delay. Due to the Corona virus, the access to the Lab is a limited. In fact,
it's good business for our Lab-Network vendors, as we had to replicate the Lab to
various colleagues at home... ;-)
However, the result of testing is exactly as expected. This is the NOTIFY for the
SUBSCRIBE from the UE to the S-CSCF (this one is correct):

But for the P-CSCF to the S-CSCF, we are missing significant parts, which makes the NOTIFY
invalid:
