22.6. Multiple Queues, Multiple Sites

Now, let’s get creative and use the various tools we’ve discussed in the previous sections to build a distributed queue infrastructure. Figure 22-8 illustrates a sample setup where we have five Asterisk servers being fronted by another cluster used to distribute/route the calls to the various queues we have set up. Our ITSP sends calls to the routing cluster (which could be something like Kamailio, or even multiple Asterisk servers implementing DUNDi or some other method to route and distribute calls), which then sends the calls as appropriate to one of the three Asterisk systems we have our queues configured on. Each server handles a different queue, such as sales, technical support, and returns. These servers in turn use the agents located at two separate physical locations. The agents’ devices are registered to their own local registration servers (which may also perform other functionality).

Note:

We are not showing all aspects of the system, in order to keep the diagram simple, but in this case we would be using the XMPP distributed device state system as we’re implying that the agents are distributed across multiple physical sites.
