it seems asterisk course are common in India and it is easier to cheat than
to apply.

If you are really trying to serve 1000 phones, beside the usage of SIP or
analogue phones via channel banks, I think it will be better to not handle
all the load on a single server, but to spread the phone among multiple
servers. The best will be to have multiple asterisks working together using
realtime extensions. It is not difficult to make.
