Thank you - At first glance it seems to have done the trick.

Never heard of this method, are you sure this works for SIP, sound more
like for ISDN (look at packet captures).

But the/a standardized method is to use the P-Asserted-Identity and
Privacy headers (rfc3325). This should work if you set in the peer configs
in sip.conf on both sides:
sendrpid=pai
trustrpid=yes

Or you can do header manipulation/getting/setting manualy if desired.
