I couldn&#39;t get the gateway to work with register=false.   I took the hint from Brian and scraped the gateway idea and put this in my dialplan.<div><br></div><div><div>  &lt;extension name=&quot;gateway&quot;&gt;</div><div>
    &lt;condition field=&quot;destination_number&quot; expression=&quot;^(\d{10})$&quot;&gt;</div><div>      &lt;action application=&quot;set&quot; data=&quot;effective_caller_id_number=${outbound_caller_id_number}&quot;/&gt;</div>
<div>      &lt;action application=&quot;set&quot; data=&quot;effective_caller_id_name=${outbound_caller_id_name}&quot;/&gt;</div><div>      &lt;action application=&quot;bridge&quot; data=&quot;sofia/external/$<a href="mailto:1@gateway_url.com">1@gateway_url.com</a>&quot;/&gt;</div>
<div>    &lt;/condition&gt;</div><div>  &lt;/extension&gt;</div><div><br></div><div class="gmail_quote"><br></div></div>
