Summary:                    [patch] IAX does not allow CALLERID(num) contain
non-numbers.
Description: 
( I already explained the issue here:
http://lists.digium.com/pipermail/asterisk-dev/2009-August/039257.html )

The thing is that IAX channel driver "shrinks" (ast_shrink_phone_number)
caller number. Which was probably the good thing before. However nowadays
when you have Skype support integrated, skype names passed via
CALLERID(num) get damaged.

I believe that only drivers which know they can not pass arbitrary number
(like DAHDI for example) should do shrinking of number before sending out.
While inside Asterisk (or relayed to another Asterisk with SIP/IAX) we
should presever original number.

Obviously I can create a patch for chan_iax which removes the shrinking
because this patch is trivial. However issue may be more global and affect
other drivers so I believe it is better to hear from Digium guys first -
maybe they have another opinion about how to solve that issue or do not
consider it an issue at all :)

---------------------------------------------------------------------- 
Hmmm, I'm almost thinking we should have a function or something that just
turns off all shrinking instead of doing the shrinking. That way existing
setups that require the shrinking to work as-is are not disturbed, but at
the same time allow the administrator to get around the CALLERID()
shrinking. Perhaps we could do something like:

exten => start,n,Set(CALLERID(shrink)=<yes|no|1|0>)

Thoughts?

This is getting to the point we should move this to the -dev list.
