[asterisk-users] MeetMe Hints

[Paul Dugas]

I suspect the issue I'm having is more specific to the MeetMe app but
that's just a guess.  app_meetme.c (in 1.6.1.6) calls

  ast_devstate_changed(AST_DEVICE_INUSE, "meetme:%s", conf->confno)

when the first caller enters a conference and

  ast_devstate_changed(AST_DEVICE_NOT_INUSE, "meetme:%s", conf->confno)

when the last caller leaves.  Running "core show hints" shows the
meetme:600 as Status:Unavailable most of the time after a conference
ends.  Occasionally, it'll show Status:Idle.  I guess I'm wondering
where the hint could be getting changed to Unavailable since it
doesn't look like the MeetMe app ever sets them this way.

I wonder if it's a result of my using an extension pattern.  AFAIK,
the 600 at dialtone hint is created from the _60X at dialtone pattern when
the first station subscribes.  I wonder if these polycom stations are
unsubscribing or timing out thus removing the pattern-generated hint.
I'll try a statically configured hint to see if that's the issue.

I also wonder if there's any logic elsewhere that would ever set the
initial hint status for a meetme.  With a brief look at app_meetme.c,
I don't see where it updates the device state except on join/leave.
