asterisk users - Nov 2009 - Channel Variable

Hi

I have been using the CHANNEL variable as a way of checking if a user is allowed
to make outgoing calls, and what their source caller ID should be (these values
are in a database).
This works all of the time with SIP and most of the time with IAX, however
sometimes with IAX the channel variable seems to be wrong.
I have been using Zoiper as my IAX client and Asterisk 1.6.2.0-rc6.

For the sake of debugging I have "Verbose(1,Outgoing Call Handler
${CUT(CHANNEL,-,1)})" in the (internal - not default) dial plan.

Most of the time the channel variable is "IAX2/10007" which is the
desired behaviour (with 10007 being the IAX username) but some of the time
"IAX2/192.168.1.111:4569" is shown instead.

I would like to know why this is happening and if there is anything that can be
done to make it show the "IAX2/10007" form every time?

I realise that I could use ${CDR(accountcode)} instead, and as it happens this
returns the correct account code value in both cases. However, I wanted to be
able to do this on a per-channel basis and multiple channels currently share a
common accountcode.

Any ideas what's going on here, is there something obvious I'm missing?

Thanks in advance.

Regards,
Nic

I believe ${IAXPEER(CURRENTCHANNEL)} should help you with the current
IAX2 name ... you can make DumpChan() to understand what kind of channel
variables you can use there.
