1.4 and onwards supports H.264. 1.2 didn't.

I've had a bunch of Grandstream GXP3000's for some time now - just for 
friends and family. (Mostly for grandparents who can barely use a PC, so 
Skype is out of the question, but can dial a phone to see grandchild 1000 
miles away)

They're mostly OK, although I'm sure there is some codec negotiation 
issues with either the phones or asterisk, and maybe the latest firmware 
for the GXV3000's is suspect. I've also tried my Nokia N900 and Ekiga. The 
N900 supports H264, but Ekiga needs an extra codec plugin. Issues I see 
involve no video or one-way video which I'm sure is something doing the 
wrong thing with regard to codec negotiation.

As for recording video - sure - works a treat and you can play it back to 
a non video device when you just get audio.

Personally, while video conferencing does seem to work (well, mostly), I'm 
not convinced the business world is ready for a videophone on everyones 
desk, but who knows what will happen in the future...
