Have a customer that has a large site wanting IP Office IP500 with 3- 23 Channel PRI's. All calls to main number will go through auto attendant first before live body. VM Pro maxes at 30 Ports and customer is expecting high call volume 2 PRI's will be strictly incoming (46 channels) the customer wants to make sure that he has adequate VM Ports for the incoming as wells as to do light selective call recording max of 2-3 at one time plus people getting messages through phones. Is it possible to use a duvoice 48 port for the VM and use VM Pro for the call recording functionality. I knnow that 48 ports is over kill for 128 stations but this customer is very unsure that 30 is enough and will not use just VM Pro alone. Any suggestions would be appreciated. Customer also has a call manager qoute and will not go that route due to pricing.
