Abstract
Call services are getting more popular these days as
new call processing technologies like VOIP are introduced
to the market and Internet is being accepted by masses.
It is becoming difficult for the equipment vendors to
support all possible call services and allow the end
users to subscribe them independently. This is because
the number of possible combinations of the call services
is very high. In order to facilitate this, there is
a need to support the basic call features (like call
forwarding, sending SMS/email etc) by the vendors and
allow the service providers to enable the end-users
to personalize their call services. This leads to another
advantage of saving the cost of manufacturing as the
manufacturer need not worry about the possible call
services, rather, the manufacturer can just implement
the basic call features (like providing JCC APIs) and
leave the customization to the service provider / end-user.
This white paper proposes an architecture that allows
the end user to personalize their call services. It
uses the call processing language (CPL), a lightweight
extensible language, which is being standardized by
IETF.
