Re: [Users] uac_replace_from() not work for Linksys ATA

Howard,
it looks fine, but you really do not have to alter the from if your GW supports RPID hdr. FROM mangling is something very expensive from processing point of view and you should avoid it if possible. 


you can get rid of the uac_replace_from() - the RPID will be added all 
the time (even if it was not originally present).

Hi Bogdan,

Could you confirm what i have done here is correct please?

route[5] {
       if (search("From:.*<sip:090[0-9]{5}")) {
               uac_replace_from("anonymous","sip:[EMAIL PROTECTED]");
               remove_hf("Remote-Party-ID");
               append_hf("Remote-Party-ID: \"Anonymous\"

<sip:[EMAIL PROTECTED]>;party=calling;screen=yes;privacy=full\r\n"); 



       rewritehostport("gatewayip:5060");
       route(1);

}

I have used uac_replace_from just incase sip header not contain rpid.

Howard

Hi Howard,

in this case is simple. If RPID hdr is used you don not have to change
the FROM hdr anymore.

To replace the RPID hdr, use remove_hf() see textops module to remove
the hdr and append_hf() to add a new one.
