Hello, I would like to discuss the implications of forwarding REFER to the ITSP. There are some ITSPs that support REFER ( notably bt.com). If we exploited this capability, that could result in a better user experience. For example, this would have the effect of the caller hearing Ringing on blind transfers assuming that the inbound INVITE has an Allow: REFER. Note that in general the ITSP may not Allow:REFER as it may well be dealing with an endpoint that does not handle REFER ( such as a PSTN phone ) so the user may not hear RINGING on blind transfer anyway.
Is XECS-1849 worthwhile? If you are calling pbx to pbx, I can see XECS 1849 being worthwhile. Questions: Are we better off simulating RINGING using our park server for a uniform user experience or should we forward REFER to the iTSP for In-DIALOG refers received from the PBX? If so, we also need to be able to handle inbound REFER from the ITSP (which adds more complexity to the code). Is the current solution of turning off MOH on the phone and turning it on for sipxbridge so that MOH plays till pickup for blind transfers adequate for this release? Your opinions are solicited. Thank you. Ranga -- M.
