[asterisk-dev] AST_CONTROL_MUTE/UNMUTE

[Nick Lewis]

I would like to add a builtin feature for muting a call. Initially I
intended to add all the new code into features.c but I now think that
each of the channel technologies should create their own outgoing mutes.
This is because in some technologies it may require more than just
sending silence (e.g. interrupting transmission and informing downstream
systems).

I therefore propose the new control frame types of AST_CONTROL_MUTE and
AST_CONTROL_UNMUTE. When features.c detects a mute request (via DTMF) it
may inform the channel (or channels) that that need to be muted with an
AST_CONTROL_MUTE frame and the mute may then be implemented in a way
appropriate to the technology

May I please have your comments on the suitability of such an approach
