The current implementation is a Lucent Intuity Audix system running on SCO Unixware system (let the joking ensue) The system is no longer supported by the installers and the only choice offered for a redundant system is a complete replacement with a price tag upwards of $20,000. We are looking at replicating the current system, but hardware for it (PXO, cards etc.) is hard to come by. I've considered suggesting something like Asterisk but I've never personally seen a voicemail-only implimentation. Can anyone point me in the right direction for either keeping the old system going (new hardware, etc.) or failing that, suggestions for a drop-in replacement system, preferably utilizing free software."
