[Freeswitch-users] Why is transfer not resulting in a reINVITE?

I am starting a call with OPUS only on the B leg, the call starts fine with inbound-late-negotiation, and OPUS is sent back on the A leg. However, the call is then transferred to a user with OPUS and VP8 video with the new INVITE, but nothing ever is sent back to the original A leg to update VP8. Is it possible to send a reINVITE back so I can update the SDP with VP8 on the original A leg?
