[OpenSER-Users] Doesn't "proxy_authorize()" allow credentials if "From" == "Anonymous" <sip:anonymous at anonymous.invalid> ?

Hi!

Do you have the domain hardcoded in the authenticate function? If not 
openser tries to detect it from the from header (anonymous.invalid) and 
thus may not find the authorization header.
