<p style="margin: 10px 0 0 0">Before looking any further here, you should make sure that you have gathered enough information from Asterisk to know what your issue is. It is suggested that you perform the following actions at the Asterisk CLI:</p>
<ul style="margin: 10px 0 0 0">
<li> <code style="font-family: monospace">core set verbose 4</code> </li>
<li> <code style="font-family: monospace">core set debug 4</code> </li>
<li> <code style="font-family: monospace">pjsip set logger on</code> </li>
</ul>
<p style="margin: 10px 0 0 0">With these options enabled, this will allow you to more easily see what is going on behind the scenes in your failing scenario. It also can help you to cross-reference entries on this page since several debug, warning, and error messages will be quoted here.</p>

</div> <p style="margin: 10px 0 0 0">In this example, the URI in the From header is "sip:eggowaffles@127.0.0.1:5061". The user portion is "eggowaffles", so Asterisk attempts to look up an endpoint called "eggowaffles" in its configuration. If such an endpoint is not configured, then the INVITE is rejected by Asterisk. The most common cause of the problem is that the user name referenced in the From header is not the name of a configured endpoint in Asterisk.</p> <p style="margin: 10px 0 0 0">But what if you have configured an endpoint called "eggowaffles"? It is possible that there was an error in your configuration, such as an option name that Asterisk does not recognize. If this is the case, then the endpoint may not have been loaded at all. Here are some troubleshooting steps to see if this might be the case:</p>
<ul style="margin: 10px 0 0 0">
<li>From the CLI, issue the "pjsip show endpoints" command. If the endpoint in question does not show up, then there likely was a problem attempting to load the endpoint on startup.</li>
<li> <p style="margin: 10px 0 0 0; margin-top: 0">Go through the logs from Asterisk startup. You may find that there was an error reported that got lost in the rest of the startup messages. For instance, be on the lookout for messages like:</p>
<div class="preformatted panel" style="border-width: 1px;">
<div class="preformattedContent panelContent">
<pre style="margin: 10px 0 0 0; margin-top: 0">[2014-10-13 16:25:01.674] ERROR[27771]: config_options.c:710 aco_process_var: Could not find option suitable for category 'eggowaffles' named 'setvar' at line 390 of

</div>
</div> <p style="margin: 10px 0 0 0">In this case, I set an endpoint option called "setvar" instead of the appropriate "set_var". The result was that the endpoint was not loaded.</p> </li>
<li>If you do not see such error messages in the logs, but you do not see the endpoint listed in "pjsip show endpoints", it may be that you forgot to put <code style="font-family: monospace">type = endpoint</code> in your endpoint section. In this case, the entire section would be ignored since Asterisk did not know that this was an endpoint section.</li>
