<div>Hi Colin,</div>
<div> </div>
<div>You should use </div>
<div>externhost=<a href="http://yourhost.somethingddns.com">yourhost.somethingddns.com</a></div>
<div> </div>
<div>and you should put the <strong>local network parameter </strong>in your sip.conf. This will identify that your local lan doesn't need to use the "externhost" parameter when you try to connect internally- and asterisk should just work fine.
</div>
<div> </div>
<div>regards,</div>

<br>address as the reply-to regardless of the NAT requirement of the phone<br>in use. In other words it offers up the external address for internal<br>calls. All data flows through the Linksys when addressed to the public
