I am a complete newbie to asterix. Our company currently provides telephone connections to about 500 users using a Coral IPX system from Tadiran systems. The existing system has been maxed out for number of connections. We would like to add to the existing system to add more capacity in terms of the number of connections and also to provide other services like voicemail, caller id etc to the users.
My question to all asterisk gurus is - Is it possible to expand the capacity of an existing system using an Asterisk based solution?
What sort of hardware would we need in the Asterisk system and our existing exchange?
