Hello A softphone sends the REGISTER request (adding or refreshing a binding) to a Registrar and receives 200 OK response. This response, as specified in RFC 3261, part 10.3, step 8, MUST contain Contact header field values enumerating all current bindings.
Recently I met a strange server, which is responding to the REGISTER requests (adding or refreshing a binding) with the 200 OK response *without* any Contact header fields. I understand that such responses are incorrect, but I must choose the best way how my softphone should handle them. Two opposed variants are: 1) interpret 200 w/o contact as signal from the server that it did not registered my contact (i.e. handle it the same way as 403 response); 2) interpret 200 w/o contact as successfull registration of the contact which the softphone tried to register. Which of these variants is more correct and user-friendly? -- With best regards, Igor Vanin, St. Petersburg, Russia mailto:[EMAIL PROTECTED] http://gpmail.spb.ru _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
