The main designation of this scenario is to check out, whether calling side
which uses tel scheme for From/To/Diversion/PAI headers, gets them fixed properly to SIP URI.
Particularity of this scenario is, that A side gets redirected with 302 Temporarily Moved.
Other than that we check out, whether Proxy doesn't admit usage of double Diversion headers present at the same message,
when a new INVITE has been generated by Proxy after receiving the 302.
