Hi everyone, Occasionally (with no set pattern), I get *"SIP/2.0 407 Proxy Authentication Required" *from iCall when trying to termiate to their international gateways. I have tried direct IP termination as well as SIP register but both just fail with above message whenever they want. Specially in register mode where the user is registered and both userid and password are good and they have been good yesterday, today they fail and the next day they work. What could be the reason?
