asterisk users - May 2005 - Default caller ID

Hi,

I've been looking at the problem of the default caller ID.  When a call 
comes in with no CID or witheld it's always set to 'asterisk' which
is
what the phone displays.  I've been looking for an option to change that.

The only place I can find is DEFAULT_CALLERID in chan_sip.c.  This is 
set by the 'callerid' option in the sip.conf.

However the documentation states that this overides outgoing caller ID 
and I don't want to set that (OTOH the code implies it's only a default 
- chan_sip.c line 4163, plus the variable name is default_callerid).

The CDR records a blank callerid from the zap channel, so it's not being 
set to 'asterisk' there - it does appear to be in the sip code that
it's
being munged.  I'd rather it stayed blank & let the phone handle it or 
say something meaningful 'Unavailable','Withheld', etc.

In chan_sip.c, set the following:
static char default_callerid[AST_MAX_EXTENSION] = "Unknown";

and recompile.

That will make the phone display "Unknown" instead of
"asterisk".

I've been doing that for around a year - works fine.
