User management

I’m planning to setup asterisk to provides IP tel’ between 5 companies around the world.
One of the main issues is user management ~200 users.
What will be the best way to manage it?
Create Delete and Password etc.

There are several very good GUI’s out there most of them free and open source.

The other option is to use realtime and create your own scripts to add/update/delete the tables as necessary.

Can I integrate Asterisk with my Active Directory or Radius server?

I don’t think it has ever been done before (that I have seen on the lists) but never say never… I do not have a lot of experience with either but I am sure that it can be done.

Thanks for your reply,
