Description

Settings has been introduced to select between two different call transfer behaviours.

Consider the following flow:

A calls B
B picks up
A and B converse (A and B have an confirmed dialog)
...
B puts A on hold
...
B calls C
C is ringing, but does not yet pick up (B and C have an early dialog)
B transfers A to C:
  B sends C a CANCEL (only if attended_transfer_on_ringing == off (old behaviour))
  B sends A a REFER without replaces.
  A sends an INVITE to C
...
A and C converse

So setting this value to "on" will avoid the CANCEL request and thus avoiding a
possible "missed call entry" in some environments on party C.
