Re: out of dialog requests

Hello,

have you considered using the dialog module function for that?

Cheers,

Henning

Subject: [SR-Users] out of dialog requests

Hi,

I'm trying to send a refer from a rtpengine dtmf event, its mostly working but the uac_req_send always seems  to append new tags for the from /to even though I specify the origionals in the .

The far end uses the tags and the callid to match the dialogs so these need to be in the refer.

Example

        # REFER to callee
        xlog("L_INFO", "Sending REFER using from uri $var(to_uri)\n");
        $uac_req(method)="REFER";
        $uac_req(ruri)="sip:"+$var(to_uriU)+"@"+$var(SourceIP);
        $uac_req(furi)=$var(from_uri)+";tag="+$var(fromTAG);
        $uac_req(turi)=$var(to_uri)+";tag="+$var(toTAG);
        $uac_req(callid)=$var(callid);
        $uac_req(hdrs)="Refer-To:" +  $var(conf_uri2) + "\r\nReferred-By: " + $var(to_uri) + "\r\nContent-Length: 0\r\n\r\n";
        uac_req_send();

Is this possible?

Thanks for your help

Regards

Rob
