[Asterisk-Users] Server Load/Capacity

[Waldo Rubinstein]

I was reading up on DUNDI and although it sounds like it would solve  
some of my problems, I don't know if it will do everything I want to  
do. For example, among the things I wanted to do is something like:  
the call director will have access to a database that will tell it  
which server a particular agent is logged in. Then, someone like a  
supervisor, could request the call director that he/she wishes to  
monitor (zapbarge or agentbarge) the agent's conversation and the  
call director will "intelligently" know where to direct the  
supervisor to monitor the call.

Assuming this setup works in general, I don't even know if I'm going  
to be able to do things like that. If you know, let me know please.

Thanks,
Waldo
