    <font face="monospace">Hi,<br>
      <br>
      So the error log is about the "remote contact", but the return
      code is -1 ?? (which according to doc [1] means invalid cseq).
      Checking the code, you should have get a -2 ret code in
      correlation to that log (see [2]).<br>
      <br>
      Now, based on the error log, I see that the dialog module retained
      the <a class="moz-txt-link-rfc2396E" href="sip:asterisk@1.1.1.28:5060">"sip:asterisk@1.1.1.28:5060"</a> URI (from a received Contact
      hdr), but it gets from the other party (as RURI) a different
      value, the <a class="moz-txt-link-rfc2396E" href="sip:asterisk@1.1.1.28:5060;user=phone">"sip:asterisk@1.1.1.28:5060;user=phone"</a> . And according
      to RFC3261 [3], that extra "user" URI param makes the URI not to
      match anymore - see chapter " 9.1.4 URI Comparison"<br>
      <br>
    </font><br>
    <pre>o  URI uri-parameter components are compared as follows:

         -  Any uri-parameter appearing in both URIs must match.

         -  <b>A user, ttl, or method uri-parameter appearing in only one
            URI never matches, even if it contains the default value.</b>

Thanks. I hadn't noticed before but yes, I'm seeing this:

ERROR:dialog:dlg_validate_dialog: failed to validate remote contact: dlg=[<a class="moz-txt-link-freetext" href="sip:asterisk@1.1.1.28:5060">sip:asterisk@1.1.1.28:5060</a>] , req=[<a class="moz-txt-link-freetext" href="sip:asterisk@1.1.1.28:5060;user=phone">sip:asterisk@1.1.1.28:5060;user=phone</a>]

I can't see anywhere in the SIP trace where that contact URI appears
*without* user=phone in it so I don't understand why that's happening.

Cheers,
Kingsley.

        <pre class="moz-quote-pre" wrap="">Hi Kingsley,

According to the docs [1], the "-1" ret code means "No  SIP message". Do you see any parsing errors in the logs, while doing the validation?

          <pre class="moz-quote-pre" wrap="">Hi,

Using OpenSIPS 3.1.5 I'm getting validate_dialog() returning $rc=-1 on
re-invites.


I have this in opensips.cfg:

modparam("dialog", "dlg_match_mode", 1)


The top of route() looks like this:

route {
        if (has_totag()) {
                if (is_method("ACK") && t_check_trans()) {
                        t_relay();
                        exit;
                }

                if (!loose_route()) {
                        send_reply(404, "Not here");
                        exit;
                }

                if (!validate_dialog()) {
                        xlog("L_WARN", "Ignoring $rm from $si due to invalid dialog; rc=$rc\n");
                }


I've attached an (anonymised) SIP trace. OpenSIPS isn't responding to
the reinvites as I'm seeing "Ignoring INVITE from (address) due to
invalid dialog: rc=-1" (as per the xlog above).

Is there something wrong with these re-invite messages, or something
I'm doing wrong in OpenSIPS?

Cheers,
Kingsley.
