[Serusers] SER Proxy auth

[E. Versaevel]

The registration/authentication to the gateway works fine, the problem
was/is that asterisk changes the From: username from erikje at iptel.org to
asterisk at ser.box however, asterisk only does that with non numeric
usernames, so 3400009525 at iptel.org gets changed in 3400009525 at ser.box, which
is not a problem. 
So I just have to use numeric usernames :)

Kind regards,

E. Versaevel

I am not sure I understand your description and the problem. If SER
gets the INVITE then registration with the PSTN gateway works (I think
that was the original problem).
