[OpenSIPS-Users] Registered trunks

[Mike Tesliuk]

Hello Pat,


I think that you can ask them to set the From Name as the callerid so
you can use transformation to take de information [1]


Example:

                xlog("FROM NAME: $(hdr(From){nameaddr.name})");
                xlog("FROM USER: $fU");

       

Result (on log):


l 24 22:06:51 opensipsHomolog2 /usr/local/sbin/opensips[7960]: FROM
NAME: "1016"
Jul 24 22:06:51 opensipsHomolog2 /usr/local/sbin/opensips[7960]: FROM
USER: 101600000393



After the authentication you can use the uac_replace_from[2] and change
the callerid that you send you carriers.
