I'm trying to configure a SIP to Gizmo5 from my lab IOS voice gateway. Inbound calling is working just fine, as is outbound calling - so long as it's not a toll call. If I place a call that would incur charges I get a recorded message from Gizmo5 saying that this call requires calling credits. If I debug the SIP call I can see the router try to place the call without authentication, get a 403 error and then place it again with authentication.<br>
<br>Has anyone else tried a SIP trunk to Gizmo5 and gotten it to work? I tried contacting their support, but they have not responded besides sending a boilerplate answer and a link to their SIP configuration page. Their knowledge base basically says that device configuration is outside of the scope of their support anyway.<br>
<br>Cheers,<br>Adam<br>
