Short and sweet: I am attempting to REFER and existing call to another UA using a REFER with an imbedded REPLACES header in the REFER-TO header. FIFO accepts the REFER and the call is set up, however the REPLACES header is dropped between the REFER and the INVITE. 1) Has anyone been able to get a REFER with REPLACES to work with SER? a. Am I doing something completely friggin' stupid?? 2) Is this a SER bug. or a FIFO bug. or neither?
