That may be the case but it really has no bearing on this callerid=yes
issue.  The issue is that Asterisk waits for caller ID info before
sending the call to the dialplan.

Landlines, at least mine, do not do this, if you wish to see the
caller ID info you have to watch the ringing phone for two to three
seconds.
