From: "Jitendra Singh Bhadoriya" <[EMAIL PROTECTED]> In my scenario the Refer-To URI was in the format 'sip:[EMAIL PROTECTED]
Where the DNS was not able to resolve the domain-name 'domain.com' of the Host and so the client was not able to send the request out. I follow Paul... I think the best course is to accept the REFER, because it is syntactically correct. After that, the question is what responses are or would be obtained in response to "INVITE sip:[EMAIL PROTECTED]"? There would be no 100, of course, because the INVITE can not be sent and so would not get a 100 response. (Although the original requester should not be confused by a NOTIFY of a 100.) But if the UA were to attempt such an INVITE from some other cause (e.g., user dialing), what error would the SIP stack present to the application layer? The most likely response would be 404 Not Found, which gives the original request a pretty good idea of the problem. 408 Request Timeout is OK, as almost any sort of transport failure can result in 408's at some point in the transaction.
