Coder Parameters
Coder	Manual or	Determines whether selection of

	matic	When Automatic is selected, the
		local and remote voice channels will
		negotiate the voice coder to be used
		by selecting the highest bandwidth
		coder supported by both sides
		without exceeding the Max
		Bandwidth setting. G.723, G.729, or
		G.711 are negotiated.
Selected	G.711 a/u	Select from a range of coders with
Coder	law 64	specific bandwidths. The higher the
	kbps;	bps rate, the more bandwidth is
	G.726, @	used. The channel that you are
	16/24/32	calling must have the same voice
	/40 kbps;	coder selected.
	G.727, @	Default = G.723.1 @ 6.3 kbps, as
	nine bps
	rates;	required for H.323. Here 64K of
	G.723.1 @	digital voice are compressed to
	5.3 kbps,	6.3K, allowing several simultaneous
	6.3 kbps;	conversations over the same
