You would need to send me a screenshot of the Asterisk entry for one of the phones. Just go into the edit panel and take a shot of the asterisk entry. In V6 we use a symbolic in the definition and a value in the database. Earlier versions were hardcoded in the Asterisk definition and the password field in the DB was often empty. Maybe this.
Here is how it should look under V6
As you can see the secret stanza uses the symbolic $password. The actual password should appear in the Password box in the left hand column.
