Hi Carl ,
For the incoming calls with Dialer
profile,when a call is coming in, it will get authenticated and a name will be used to bind to a proper dialer profile interface with "dialer remote-name" command.The name specified must exactly match the username provided by the remote router for authentication.
Only one remote name can be associated with a dialer interface at a time. You may change the name associated with the dialer interface by reissuing the dialer remote-name command. Issuing the no dialer remote-name command removes the remote name configuration.
When using Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP) authentication, user-name is the name of the remote device that is authenticating.
hope this helps you.
Thanks,
satish
