[OpenSIPS-Users] How to get the name-addr within a From header?

[Gordon Yeong]

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:12345688 at 192.168.136.134:5060>;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:sipp at 192.168.136.134:5060
;transport=UDP>
$var(CALLING3)=$hdr(f);  --> printed out Mr Invite-R-Us <
sip:12345688 at 192.168.136.134:5060>;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
