In my opinion as many Cisco's as I have seen go so poorly, with horrible voice quality, and outages every time the network goes down. Not to mention that the Coral Call Processor runs on a windoz server, and the licensing you have to purchase for each user, phone, voicemail box, etc. And not to mention the fact you have to continually purchase those licenses every 2 years to stay current. I know of several Cisco installs that have been replaced, and that will be replaced before the software renewal comes around.
