I have the Trio 8800, its up and running but when I try to enable SIP Authentication I get service unavailable. It is connected to a Mitel 3300 as a Gernic SIP Phone. When I add a password to the Mitel Device on the Access and Authentication tab in the SIP Password field the Trio 8800 displays the "Unregistered line" icon. I clear the password on both the Trio and Mitel and its works again.
I tried letters only mixed, numbers only everythign saves fine just can't get it to work with a SIP Password. Any suggestions on what I could be doing wrong?
