Hi
Steve is right. Better not replace the from header for accounting purpose
but add a remote-party_id. The main issue is : not all the GW are
understanding the rpid stuff but even cisco Gw are understanding it.
Again, from header field is required in various situations and alter it
could lead to problems.

Steve,
Thanks for your email and your solutions.
I tried the first method as follws:
replace ("^From:(.*)<", "From: \"XXXXXXXXXX\" <")
before I sent it to another SIP device and PSTN gateway. I did see the
new Caller ID XXXXXXXXXX in another SIP device but the Caller ID to Verison
Mobile phone showed "Unavailable No". I will check with Telco carrier to see
if we did send the Caller ID to them or not.
Also I will try your second method and update to the list later.
Thanks again.
Larry

You can do this several ways. I use to just completely replace the From
header but this screwed up call accounting (for callers with caller ID
blocking enabled) which we do in our Cisco gateways. Now I append an
Remote-Party-ID header leaving the Fromheader intact for accounting
purposes. Try one of the following:
1) replace("^From:(.*)>" , "From: \"Anonymous\"
<sip:anonymous@invalid.nowhere>");
Where the second string contains whatever you want the caller ID info to
be. This example is for caller ID blocking.
2)
if (append_rpid_hf("Anonymous
<sip:","@upenn.edu>;party=calling;id-type=subscriber;screen=yes")) {
} else {
log(1, "RPID not found\n");
};
Of course this requires other configuration items. You may also want to add
the following:
modparam("auth", "rpid_prefix", "<sip:")
modparam("auth", "rpid_suffix",
"@upenn.edu;user=phone>;party=calling;screen=no;id-type=subscriber;privacy=
off")
