Hi, Gordon!

name-addr is basically the entire header, and you can access it using $hdr(From). However, it looks like you are looking to get the From header username, that, as Grant pointed out, is returned by the $fU variable. Does this solve your problem?

    Hi Gordon,

    I believe you’re looking for the username in the From header.
    It’s the $fU variable.

    https://www.opensips.org/Documentation/Script-CoreVar-3-1#toc47

    That should give you 12345688.

        Hi guys,


        I looked up RFC 3261 <https://tools.ietf.org/html/rfc3261>. and
        the from-spec (page 229) says:

        from-spec   =  ( name-addr / addr-spec )
                        *( SEMI from-param )


        I have the following FROM tag in a SIP header.
        "Mr Invite-R-Us <sip:[email protected]:5060
        <http://sip:[email protected]:5060>>;tag=784"

        In my opensips.cfg, I got the following results using the
        compact forms, m and f

        $var(CALLING2)=$hdr(m); --> printed
        out <sip:[email protected]:5060;transport=UDP>
        $var(CALLING3)=$hdr(f);  --> printed out Mr Invite-R-Us
        <sip:[email protected]:5060
        <http://sip:[email protected]:5060>>;tag=784


I have looked through the RFC document again but could not find how one could get the "name-addr" (ie. " 12345688"). I have also
        looked through the Opensips Core variable documentation.


        Can anyone please tell me how to get the name-addr within a From
        header? What is the attribute name or compact form?


        Thank you

        Gordon
