3 Way Authentication V14 vs. V15

[ctsuser]

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.

Found out in another post, that the 3 Way Authentication Password is indeed the same as the old Authentication ID. I was able to get the service up and running again. Still I think the old label was clearer.
