Hello Pedro,

So test case is simple. asterisk is play voicemail role and kamailio is gateway.  Asterisk peer is setup and working. I think message SIP/2.0 484 Address Incomplete is some from kamailio

When Asterisk send reply back this message show up because is no $rU in header line.

I don't know how to correct it that it will full uri format line.

        if ($rU==$null)
        {
                # request with no Username in RURI
                sl_send_reply("484","Address Incomplete");
                exit;
        }

Slava.

Subject: Re: [SR-Users] message 484

I think this is the correct behavior, as asterisk server is complaining about the address/request not containing all the necesary data to process the message

Can you please elaborate with a bit more of detail? Also can use tools like   sngrep, tcpdump (or wireshark) to have a better view of the complete call flow.

Maybe that way we can help.
