As I understand ACK request is picked up by the transport layer and

Hi Michael,

Have a look at:

It seems to me that PJSIP does not support SIPS scheme in Record-Route. That

I understand this is not possible. If you use SIP you don't use TLS.
Where there is intention to use security _only_ to the next hop, protocol

If we are strict on the interpretation, then any implementation is free to
send upper/lower case. But we can see that the spec. is leaning towards the
version being implemented in the upper case. I'd say, lower-case
implementation are right as well, but are not self-respecting.
