[Asterisk-Users] Anybody has one SIP minimal configuration and one working Softphone?

[Mauro Zanin]

Hi everybody,
I'm new to this matter and I spent three days in trying to connect one SIP
Softphone to an Asterisk Box. I always get error 401 or 403...
I don't understand very well settings in Softphone program: con anybody show
me how to set up a minimal running system with no public lines or external
Proxies?

Thank you for your kind help...
Ciao
Mauro
