user-Settings: Voip-Phone -> Voxalot -> Provider

[casch]

Hi,

when I call s.o. my tel.no. is hided. I would like to change that.
I found in voxalot for advanced provider settings two 'user':

1st) 'From user' (no star - not required ?)
Which has to be my login name for my provider?
If I changed that to a tel.no., I want to be shown when I call,
my registration at my provider keeps 'pending' - correct?

Username (with star)
If I change this to the a.m. no. my Voip-phone immediately gets a server error (500),
while voxalot shows me being registered at my provider at the same time.
What I entered there is not my voxalot-name but again my provider login-name, so twice the same.

Please tell me:
what 'user' is meant for what and how I might be able to let my tel.no. shine on the phone I'm calling - if I can set this up at voxalot.

In my voip phone I have three 'users' to enter and
I have to set the first two to my login-name of voxalot (40. ..6):
Anwendername (=application Name) = 40..
Auth.name (=Authent. Name) = 40..
(If I chg. either of these two the phone does not connect to voxalot)
AnzeigenName (=display name) = calli

But nothing of these is forwarded to the other phone

Thanks in advance,
Carl
