[asterisk-users] Asterisk Configuration Complete Newbie question

[K Y Iyer]

Hello

Am starting on my Asterisk journey - am getting a single span Digium
card to connect Asterisk to our Alcatel 4400 EPABX and install about 100
VoIP instruments.

The Asterisk VoIP extensions and Alcatel digital extensions have to talk
to each other.

Am I right in understanding that

IN ASTERRISK : I have to create a config with either all Asterisk and
Alcatel extensions - which config files? extensions.conf for both with
the two types of extensions in different contexts?  Would that be the
correct way?

IN ALCATEL : List of Asterisk extensions and the PRI card to which the
calls have to be delivered.

Is that broadly correct?

Thanks very much

Best wishes

Iyer
