Currently in the input settings for the auto attendant [*] will send the caller to the Sing-In conversation.

When you hit [*] in the AA, the call is disconnected immediately, never prompting for a ID/password.

It tried mapping it to [#] or even numerical keys, and every time the call is disconnected.

I ran the port monitor utility and everything is fine but once you press [*] it says something like...

CONVERSATION SIGN IN

EVENT HANG UP

Happens both on internal and external calls.
