Steve,
Thanks for your help regardin the Caller ID in FROM field in your
previous email.
It was working with the your suggestion for 'replace' to hard-code the
FROM field.
I would like to extend it to any users which has a Caller ID (normal
phone number) mapping to SIP account and stored in Postgres database.
When someone calls from SIP device, I use exec_msg to call the external
C program which retrieves the Caller ID related to this SIP account. The
problem is how to pass this data back to SER and put into FROM field ?
Please advise,
Thanks and Regards,
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")
