asterisk users - Jun 2005 - Agents/Queues Contexts

Is there a way to define multiple contexts for agents/queues such  
that in a multi-tenant environment, there could be two different,  
say, Agents 1000?

I'm setting up a multi-tenant configuration and I'm giving each  
tenant a web-based interface to define their own agents and I  
wouldn't want to restrict one tenant from choosing an agent because  
another tenant (which the tenant has no idea about) has already  
chosen that agent id.

Thanks,
Waldo
