Proxy authentication required? 827 and voip

[simonepezzano]

Good day,

I'm moving slow steps toward voip with a 827.

I'd like to use it with a SIP, but my problem is, in the data they gave me there is this thing:

Sip Proxy: sip.messagenet.it:5061

I don't know where to put this and when I try to make a call, all I get is "proxy authentication required".

Do you have any hints?

Its like an authentication failure.So doublecheck the username and password and make sure its configured correct.
