I am new to cisco and I really need somebody to help me on this.
I need to configure the cisco voice gateway so that
i) When an user (from netmeeting) trying to call to POTS attached the gateway, he can hear IVR to ask for user and pin number.
ii) When the POTS trying to call to PSTN / other gateway, the user also have to provide user and pin info.
I attempt to use Radius server for the aboved purposes.
My questions are:
a) the aaa authentication command only applied to login, ppp or arap. Which one that I should use for these cases? The user and the voice gateway could be at the LAN instead of dial-up.
b) there are a few TCL scripts that can be used, differentiate by the way to collect user and pin info. But i do not understand what does it meant by from ANI, DNIS, NULL and null password. What are DNIS (calling number?) and ANI (where this info stored?).
c) what are accounts? Is that an user that added in User file of radius server? Is the account should be the the same as the phone number the user dial?
d) what are lines (VTY lines) and Interfaces ?
Thanks for any comment and best regards.
