      Add support for Session-ID header, REF 14596 · fb69364d
      Grzegorz Sluja authored and Yalu Zhang's avatar Yalu Zhang committed 
      According to RFC7329 there is a need for having a globally unique
session identifier for the same SIP session that can be consistently
maintained across SIP Proxies. There is a Call-ID header value already
as a globally unique identifier but in practice it is often changed by
SIP Back-to-Back User Agents. Therefore in order to provide an
identifier that will not be modified/replaced by B2BUAs a new SIP header
"Session-ID" is added.

The general concept of "Session-ID" header is that the UAC generating an
out-of-dialog request generates a new, unique value that remains
constant for the duration of the transaction, any dialog created from
that request or for a registration.
