You'll have to forgive me if this question seems stupid but my only experience with the IP Office has been the maintenance of installed systems. A customer of mine was given a IPO 500 V2 controller and he wants to use it to upgrade the pbx at a hotel he owns. I've calculated that this will require the addition of 8 Phone30 modules for the guest rooms, etc. and another Combo module in the controller for the office phones, outside lines, etc. I need to know if these can be added without having to add anything to the licenses on the controller. I was able to download a configuration from the controller and found out that it is running release 7.0 software. What do I need to see in the licensing to know if this expansion will work?
