[OpenSIPS-Users] dlg_val before create_dialog

[M S]

So I did that, and it is very strange:

    if (is_method("INVITE") && !has_totag()) xlog("L_WARN",
"$ci|route|$Ts:$Tsm|DLG_status3 $DLG_status");
            if(!rtpproxy_offer("froc")) xlog("L_WARN",
"$ci|route|$Ts:$Tsm|rtpproxy_offer failed for: $mb\n");
    if (is_method("INVITE") && !has_totag()) xlog("L_WARN",
"$ci|route|$Ts:$Tsm|DLG_status4 $DLG_status");

1

But what does rtpproxy_offer has to do with dialog?
