On the Caller User-Interface we can map 182 to "call waiting...." -----Original Message----- From: sip-implementors-boun...@lists.cs.columbia.edu [mailto:sip-implementors-boun...@lists.cs.columbia.edu] On Behalf Of Iñaki Baz Castillo Sent: Wednesday, June 10, 2009 11:49 AM To: sip-implementors@lists.cs.columbia.edu Subject: [Sip-implementors] Indicating "Call Waiting" in a 1XX response Hi, calling today to a cell phone I've seen in my mobile screen: "Call waiting in the other side" This is: the callee was using a line in his phone and it was announced in a provisional response. Does something similar exist for SIP? IMHO it would be very easy to implement: A specific header "Progress-Status: call-waiting" could be added by the callee's device to 1XX responses so the caller could display it to the user. Another option would be a new response code: "184 Call-Waiting" but it would be very complex to make it work with existing devices which basically expect 180 and 183. Opinions?
