System information

Asterisk system, and then another caller enters the sales queue on box two, no infor-
mation will be distributed between those queues to indicate who is first and who is
second in line. The two queues are effectively separate. Perhaps future versions of
Asterisk will have the ability to do that, but at this time it is not supported. We mention
this so you can plan your system accordingly.
Since queues in some implementations (such as call centers) may be required to handle
many calls at once, the processing and load requirements for a single system can be
quite steep. Having the ability to tap into the same agent resources across multiple
systems means that we can distribute our callers among multiple boxes, significantly
lowering the processing requirements placed on any single system. No longer does one
system need to do it all—we can break out various components of the system into
different servers.
