Hey Everyone

I'm  setting up a load testing scenario for my Kamailio. In order to do that i've created another Kamailio to answer "200 OK" to an Invite in order to simulate a call being answered. 

One of the scenarios I need to test is reading values from the ISUP IAM or ACM body. 

Here's the code on the Kamailio that replies with 200 : 

 $var(acm) = "06 02 04 01 2c 01 fb 0c 08 83 10 19 7c 82 12 15 00 36 01 19 40 01 00 39 06 2c c0 36 c0 40 c0 00";

        set_reply_body("$var(acm)","application/isup;base=itu-t92+;version=etsi356");

        if( is_method("INVITE") && !has_totag() )
        {
·
                xnotice("First Invite");
                send_reply("200","OK");

        }


However, when i use this and i do a pcap i get a "Message Type: Overload", which doesn't support optional parameters. 
What am i doing wrong ? Are there other methods to setup a simple ISUP part without hex ?

Thanks in advance
