Hi Sam,

some phones seem to hate phone numbers with strange characters in them;
those might be spaces, "+" signs, "-" dashes etc. and refuse to display
anything at all. Perhaps the information is there, but it is in some way
or another taken as "invalid".

You could see what Asterisk "thinks" those variables are. A

NOOP(CALLER-ID-Info: ${CALLERID(num)} / ${CALLERID(name)})

in the dialplan, together with CLI and "set verbose 10" should show you
lots of information.
