Different softswitch vendors use one or more of the different headers to
provide information, and there is not a clear common criterion to all of them
on the priority to be applied.
Moreover, ST20xx phones have a local phonebook.
Phonebook shall be always the 1st priority, but the header to look for in the
phonebook will depend on the priority of the headers.
So two new v
ariables are defined for “header priority”, default value being
as follows:
CLIPDisplayPrior
=ppreferred(1)passerted(2)remoteparty(3)from(4)
CalledDisplayPior
=dialed(1)passerted(2)remoteparty(3)
Precedence mechanism to be applied is:
When a call is received, phone will check which is the header with the
highest priority present in the INVITE ("presentation candidate") comparing
with
CLIPDisplayPrior
. Once found, will check whether this address exists in
the local phonebook or not. If it does, it will present phonebook info,
otherwise, it will present the "candidate".
For outgoing calls, it is the same: check highest priority (dialed digits or
header in 200 OK), to determine “presentation candidate” comparing with
CalledDisplayPior
. Will use that to check the local phonebook. If existing in
the phonebook, it will present phonebook info. Otherwise, it will present the
"candidate".
