I doubt that you can do this with REFER. While it's true that you can use BYE as a trigger, but proxy cannot absorb BYE and generate in-dialog REFER instead, so that the device will get both BYE and the new REFER transaction outside of dialog. Its behavior in such case is undefined at best. Regards, -- Maksym Sobolyev Sippy Software, Inc.
