<div class="gmail_quote">We are attempting to configure SIP trunking between asterisk 1.2.22 and a Mitel 3300 CX box. The Mitel machine will gateway to the PSTN for us. I found this earlier post about doing this from July:<br>

<br>Unfortunately the promised configs never came ;(. We're having the exact reverse problem: we can register with the Mitel box just fine, and we receive calls from it correctly. However all attempts to make outbound calls from asterisk to the Mitel machine fail with a 404 Not found.<br>
<br>The following is a fragment of our sip.conf (the extensions.conf config is just a single Dial(SIP/thenumber@mitel-outbound) entry):<br><br>register => <a href="http://450:1234@192.168.100.2:5060/450" target="_blank">450:1234@192.168.100.2:5060/450</a><br>
<br>[mitel-outbound]<br> type=peer<br> secret=1234<br> username=450<br> host=<a href="http://192.168.100.2" target="_blank">192.168.100.2</a><br> fromuser=450<br> fromdomain=<a href="http://100.110.0.200" target="_blank">100.110.0.200</a><br>
insecure=very<br>
nat=no<br> context=mitel<br> port=5060<br><br>In the above: username/password/host are 450, 1234, and <a href="http://192.168.100.2" target="_blank">192.168.100.2</a> respectively. (names changed to protect the innocent). The box is at <a href="http://100.110.0.200" target="_blank">100.110.0.200</a> (again..)<br>
<br>Has anyone else had a similar problem with receiving 404's on outbound calls to Mitel boxes? We found the Mitel doesn't respond at all when we change the host line above, presumably because the From header in the sip changes to not include the Username correctly. I can't get any auth headers to come in the initial INVITE, although with some digging I found out they would go out if the Mitel had responded with a 401.<br>
<br>Any help is appreciated.<br><font color="#888888"><br>Robert Bedell<br>SienaTech<br><br><br><br>
