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:
