The authentication digest is "" which means that Voxalot is challenging your end point for credentials.

If you look at the "From" address it is a URI

My first question is whether or not your ATA / Device is authenticating with the Voxalot server properly?

407: Proxy Authentication required

My first thought was that requires authentication and provides the termination of these calls only to their customers, so I posted to the forum about this issue.

German Toll-Free Numbers: ENUM resolves to sip:49800\

evilbunny, the mod of this forum, whom I also sent a logfile showing this error message pointed out that the root cause must be within Voxalot.

When calling the toll free number directly ( the call wents through properly.

Now my question to the Voxalot Team:
Can you find out the root cause for this issue?

Here is the trace:
