Hi,
In Caller preferences RFC3841, 5.2. Feature Set Preferences,
" When only "explicit" is present, it means that all contacts
provided by the callee will be used. However, if the contact isn't an
explicit match, it is tried last amongst all other contacts with the
same q-value. The principle difference, therefore, between this
configuration and the usage of both "require" and "explicit" is the
fallback behavior for contacts that don't match explicitly. Here, they
are tried as a last resort. If "require" is also present, they are never
tried"
my question is if "explicit" is present in accept-contact header of the
request , can a contact from a callee be used if doesn't match at all.
and also i couldn't make out any behavioral difference b/w
accept-contact header with explict and absence of both explict and
require in a request.
Regards
Subramanya
