Mute a channel instead of user number using command meetme m

Hi,

I want to mute a particular channel using meetme command
eg:
meetme mute 2000 SIP/912345

Meetme mute only works with userno.
like meetme mute 2000 1

Please help

SIP/912345 is not a channel, but rather a device. It is ambiguous, as multiple members could be using the same device (e.g. a trunk).
