Hi there,
i have a question regarding an INVITE containing anonymous and user=phone in the From-header like this: From: <sip:[email protected];user=phone>;tag=090142342mnb2343 RFC 3261 tells in section 19.1.1: "The set of valid telephone-subscriber strings is a subset of valid user strings. The user URI parameter exists to distinguish telephone numbers from user names that happen to look like telephone numbers. If the user string contains a telephone number formatted as a telephone-subscriber, the user parameter value "phone" SHOULD be present." As far as i understand it doesnt say that user=phone MUST NOT be present if user-uri isnt a phone number. It only distinguishes user-names from phone-numbers which look like phone-numbers if the parameter isnt present. Am I wrong? I have this case and the UAS doesnt respond anything even not a 400 Bad Request. By the way, is it okay not to send any response in such a case?
