Hi
The INVITE would also be interesting.
Does the Contact: Header in the invite contain the transport=tls
attribute?
Souldn't the 200 OK reply contain at least one Record-Route (the lowest
one) stating transport=tls?
PS: I was facing a similar issue with a commercial SBC which, when
TLS/TCP is not licensed, has the oddity to remove the transport
attribute from the contact header and send new transactions in the same
dialog without specifying transport (defaulting to UDP). So I had to
create a copy the value of the transport header to a custom t=
contact attribute, which I then use to restore the U-URI transport
attribute towards the registrar handling the CPE connection.
