If you refer to sip user agent because presence generates a request (e.g., NOTIFY), then it is ok -- I wanted to be sure will not be misinterpreted by readers that it refers to the case when using kamailio as client (e.g., for remote registrations). In other words, this function should be used if contact is not stored anywhere for later usage inside same kamailio instance (memory or database).
understood. i have never had any problems with add_contact_alias, because i don't use dialog module (the one that historically has had more problems than any other kamailio module) and my sip proxy frontends my presence server.
