*21 is a well known network service in POTS. There is a common way how to
set, active and deactivate this kind of service using an user terminal (i.e.
sip phone).
On the network service part (i.e. in ser) you would "simply" have to write a
small app that handles these kind of calls, processes what ever is needed to
be done (i.e. store the redirect number to the database) and then
rewrite/reroute the call to an annoucement server (to let the user know, if
the changes took place or not).
In addition, the ser routing would need to get extended to read a user's
redirection data (on/off, where to route to in case of on) and
rewrite/reroute if needed.
The same mechanism may also be used to handle voice mail redirection.
If some is interested in implementing such kind of feature, i would be
willing to support (mainly by conceptional and testing work).

Subject: Re: [Serusers] call forwarding and *21
If you do a search on the list, I THINK I posted a way to do
call forwarding
(the way I was doing it anyway)... there are likely other
ways. How are you
going to take input for the forwarding, though?
Will they dial *21 and it will forward to something they've
predefined on a
website somewhere? Will they dial *21 and then the number to
which they want
to forward? How do you turn it off? Etc, etc.

Can someone point me to any resources on how to
implement services
like callforwarding by pressing *21 through the users' UA?
Basically I need my users to be able to activate different services
via the phone's keys.
thank you
