[Serusers] call forwarding and *21

[sip]

Heh.. it may be a well known network service THERE, but here in the US, there
is no *21. We activate call forwarding with a *72 -- which is why I was asking
how he wants it implemented. 

In the world of telecom, there are no absolutes. :)

And yes... the way you conceptualise, this is not a trivial task. You'd need
an application that handles DTMF tones, can make changes to the SER databases,
and handle the RTP stream for purposes of playing audio and working with the
DTMF.
