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?
See Below:
Initial Call:
