Help needed regarding G.722 codec negotiation.
I have few queries regarding SDP implementation for multiple bit rates for
g.722 codec.

Query-1: à I want to negotiate g.722 codec with multiple bitrates 64 56,and
48. Then what would be SDP attributes value in Sip invite.
Query-2à if I have following codec order for negotiation, then what would be
the SDP for Sip Invite?
G.722 at 64 kbps

Query-3 à On network what flavor of G.722 codec is better at bit rates
