you also need (as stated in the bug report) the patch
10217-asterisk-unrestricted-digital-llc-11595-1.4.17.patch from
http://bugs.digium.com/view.php?id=10217
This enables LCC in chan_zap. Is this was done some time ago I do not
remember anymore who it is activated, I think you have to add the
h324m=lcc
option to zapata.conf
I remember one scenario where H324M signaling was required to be in
Bearer Capabilite AND Low Layer Compatibility. I think you can easily
extend the patches to signal both versions at the same time.
Always take a look at the outgoing SETUP message to see if it contains LCC.
PS: Please dump an incoming SETUP message for a video call - does it
contain LCC too?
