That depends on what you mean by multiple clients. If you mean multiple
customers of a single ISP, you would provision serveral PRIs through a
telco, and assign a phone number that will hunt down through all of PRIs
to find an open port.
If you mean multiple clients in the sense that you're a dial wholesaler
and you're providing service to multiple ISPs, you'd still do hunt groups
as mentioned by other posters, plus you could also assign each wholesale
client a unique RADIUS domain to allow for client-specific attributes to
be applied to dialin sessions. For example, this could be used to control
the IP addresses that are assigned a given ISP's customers.
