Is there any way to separate the signaling and media for a call across 2 FreeSWITCH servers?

Suppose that I would ideally like to transfer a call from one FS server to another, but the user agent doesn't support any kind of SIP methods to accomplish this (ex. REFER, INVITE with "Replaces" header, etc.).  Is there a way to re-route the media to another FS server while keeping the signaling anchored on the original FS?

Thanks
