[asterisk-dev] Copying channel variables to another channel

[Paul Belanger]

asterisk-dev,

I'm attempting to write, what I believe to be, a trivial patch to fix
an existing issue (https://issues.asterisk.org/view.php?id=17180).  I
figure it might be an _easy_ way to learn more about chan_sip.  I
believe I know the solution to the problem, but was looking to get
more information about 'copying' a channel variable from one channel
to another.

Back in May '06
(http://lists.digium.com/pipermail/asterisk-dev/2006-May/020713.html)
Olle talks about copying channel variables.

---
When one channel creates another channel, we copy some data to the new channel.

I've been looking in the source, but haven't found an existing
function to do this. I'm curious if we copy _certain_ channel
variables into a new channel or are we to copy all existing variables?
