Hi Subramanya Yes the contact from the callee can be used if there is no explicit match.

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.
