I guess that means that the AJAX is polling the web app
to see if there is a new call? How frequently do you poll?

We've solved this a different way, without polling - but with
AJAX.

We embed a softphone (we use ours of course) in the
web page. When a call comes in, it issues a JavaScript
callback and the normal AJAX stuff kicks in.

In the case of agents with hard-phones, we get asterisk to
ring both the hard and softphone, the agent picks up
the hardphone, but the softphone still triggers the AJAX
stuff.

In theory this should be more responsive and scalable,
but I have no figures to back that up.
