I have a Voip Provider which uses three way authentication: that is, a USERID which is the account number, and an AUTHENTICATIONID:some.user. In V14, when one selected 3 Way Authentication in the trunk setup, you could fill in the 3 Way Authentication ID. In V15 however you are only given the option to fill in another Authentication Password, which isn't really helpful in my case. Is this a bug in V15? Would there be a way to have the Authentication ID passed on to the VOIP server during registry? Thanks.
