If set to 1, encode DTMF in the active

 

 

 

RTP stream, otherwise, DTMF may be

 

 

 

encoded within the signaling protocol only

 

 

 

when the protocol offers the option.

Chord-Sets <chord/>

Chord-sets are the building blocks of sound effects that use synthesized rather than sampled audio (most call progress and ringer sound effects). A chord-set is a multi-frequency note with an optional on/off cadence. A chord-set can contain up to four frequency components generated simultaneously, each with its own level.

There are three blocks of chord sets:

•callProg (used for call progress sound effect patterns)

•ringer

•misc (miscellaneous)

All three blocks use the same chord set specification format.
