Help me with my maths here, I am trying to pitch a migration to my boss. We have 5 outside sales reps that share a 10,000 minute plan and a 10GB. I figure at least 80% of that can be done using 3CX on their cell phones. Those 8,000 minutes can be translated into about 5GB of data, and I am going to estimate that at least 50% of that can be offloaded to available wifi rather than Cellular Data. Any calls to and from their desks (and then to their cell phones) from customers will use SIP minutes and data, so that 8,000 minutes saved from the cell bill needs to be accounted for in the SIP package I go with, right?
