[Asterisk-video] Video issue on 1.4.6

[Jerry Geis]

I have 3 phones

P1 is a non video phone - grandstream
P2 is a Grandstream GXV3000
P3 is a Grandstream GXV3000

Using P1 to place a call to P2 I get audio only.
Then on P1 a transfer the call to P3 and I still only get audio.

At this point shouldn't the two video phones P2 and P3 say
to each other we are video and so the video stream startup???

This is not working at this time?
OR is there something I am missing.

Thanks,

Jerry
