Yes that's right, but there is a reasonably significant improvement in video quality of you go MPEG-4
Of course h.264 (MPEG4 Level 10) would be the best, but Radvision (AFAIK) do not support that.


	I know that H.324m makes the provision of using MPEG4 video as codec but 
	I have not seen a single terminal that support it.
	  

Nokia 6110, Motorola Razor V-series,  Nokia 6220 etc all support MPEG4.
In fact most of the newer (<3 years) video mobile phones do.

		Hi,
		
		I have built asterisk with video support and ooh323.
		
		Using a Radvision gateway, I can place a 3g call and play video using
		h.323 signaling with the h.263 video codec.
		
		ooh323 does not support the mpeg4 codec when it negotiates terminal
		endpoint capabilities.
		
		Does anyone know of a way to support the mpeg4 codec with asterisk using
		h.323 signaling?
		
		Thanks,
		
		Andy
