For codecs that are able to change sample rates, the lowest and highest sample rates MUST be reported (e.g., 8000;16000).
rlq value: need algo to compute it
3.4 overload avoidance?
a. Send only one report at the end of each call. (audio | video?)
b. Use interval reports only on "problem" calls that are being closely monitored.
- The Session report when
codec change
