Seems like a significant regression in spitting things out to channel variables, instead of using dialplan functions to retrieve values when needed.

So you're thinking something like:

exten => blah,1,Answer()
      same => n,MixMonitor(file.wav,i(ID))
      same => n,NoOp(Filename is MIXMONITOR(${ID},file))

?

I'd be okay with it. The main reason I went with the channel variable approach was because of app_mixmonitor's pre-existing 'i' option. My thought was that this feels more "consistent" than providing a separate method of getting an instance-specific value.

Of course the attraction of the dialplan function route is that it is more scalable in case there are other instance-specific values that people wish to retrieve from a mixmonitor.

Thus, the MixMonitor application should not have any assumptions that the channel has only a single MixMonitor being run on it. Setting a single MIXMONITOR_FILENAME channel variable violates such assumptions by overwriting the value set from previous invocations of MixMonitor. By using the 'f' and 'i' options for MixMonitor, a user can easily manage multiple recordings on a single channel.
