[Asterisk-Users] Changing RO vars like SRC

[Anton Krall]

Guys, is there a way to set CDR vards like SRC, I tried using set but
asterisk complains they are RO vars. What Im trying to do is a small way to
let users make calls from someone elses extension but auth using a password
and seitch credential to their own so the call appears on CDR as made from
their extension and not the one they are actually using.

Is there a way to do this and somebody has done this before?
