If the Altigen is sending a SIP Register then it probably needs to be configured as a SIP endpoint rather than a SIP trunk. A SIP trunk doesn't need to register so it would just send the Invite.<div><br><div> <p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="3" style="font: 12.0px Helvetica">-Ryan</font></p> </div><br><div><html>On Apr 1, 2008, at 10:55 AM, <a href="mailto:tim.medley@moxieent.com">tim.medley@moxieent.com</a> wrote:</html><br class="Apple-interchange-newline"><div>Does anyone have any experience setting up an Altigen PBX to integrate to a CCM 6.x via a SIP Trunk?</div> <div> </div> <div>I have a SIP Trunk configured in CCM and have the SIP Digest Authentication setupas well.
