Barge In

Using the status screen, I can barge in on other extensions as the function suggest. When I do this, though, the call is muted. That's fine, but the problem is that pressing *1 does NOT unmute the call. Could this be a bug?

If you change the last line of
/etc/asterisk/extensions_hud.conf to: exten => _2X.,1,MeetMe(20000000${EXTEN:1},aqs,271721), would it work?

Thanks!
