I need help in sizing a Voice Mail system for a Fixed CO switch/network with 750K subscribers. The telco wants all busy any unanswered calls to be diverted to the Voice Mail system. Presently, an estimated 33% of the current call attempts get completed. Average traffic per subscriber is 20 call per day. I would appreciate if you could provide me with the formula/method to calculate the port requirement or point me in the direction where I may find this information.
Thank you
