[Web-meetme-users] problems with some functions like extend

[Sir L. <sir...@gm...>]

I have recently installed web meetme successfully, can create a new room,
and can monitor existing rooms and users, mute users, kick users, create new
users etc

But there are three functions inside a conference room i cannot use: Extend,
End Now and Invite.

I'm using web meetme latest version and Asterisk 1.8 and followed the basic
installation guide.

Any ideas regarding this issue?
