The fix to the rat source to make it send the cname messages to attached
vics seems to be as simple as the following (output from cvs diff -c)
*** rtp_callback.c 2002/04/01 21:45:35 1.62
--- rtp_callback.c 2002/06/12 14:00:21
*** 276,281 ****

ui_send_rtp_cname(sp, sp->mbus_ui_addr, ssrc);
+ ui_send_rtp_cname(sp, sp->mbus_video_addr, ssrc);
ui_send_rtp_name(sp, sp->mbus_ui_addr, ssrc);
However we still need a fix for the different cnames. It might be possible
to persuade vic to match cnames that only differ in the last octet of the
ip-address in the cname but it would be cleaner in the long run to
synchronise the AG node cnames as discussed earlier.
