It means doing a reINVITE that pulls you out of the signalling/media path. FS can do it:

Not sure if there's a term for it in SIP, but it sounds like this is the same thing.

If they're actually on the call to them then I guess you can unbridge, bridge them to the other parked party, then do the simplify.

does anyone know what the SIP equivalent is to "2 b channel transfer". taking an inbound and an outbound, drop operator out, and pass the call up to the telco?
 
Thanks,
