[Asterisk-Users] Web interface Suggestions

[jamesm]

    Has anyone come across any software that can control adding/editing 
SIP extension properties and perhaps dial plan properties on a context 
basis. What I mean is I would like it so an admin user from Company A 
can manipulate
properties for extensions in his context but not in another Companies. I 
know AMP does something similar
to this but from what I understand it does not allow for different users 
at different companies to control
only things that pertain to them.
