Planning · UC Budget
Estimate a 3-year UC budget across on-prem CUCM, Webex Calling, or Teams Direct Routing — hardware, licenses, carrier, SBC, pro-services, ongoing.
Budget surprises kill UC projects. This estimator gives order-of-magnitude numbers using published Cisco/Microsoft pricing patterns. It won't replace a carrier quote — but it'll stop you promising numbers you can't deliver.
Estimates show 3-year total and per-user per-month cost. Numbers are ballpark USD; multiply by 1.1-1.25 for APAC, 1.15-1.3 for Europe. Always get a carrier and Cisco/Microsoft quote before committing.
Mostly: underestimating pro services and ongoing managed costs. Licenses and hardware are on the datasheet. What isn't: the 30% pro services load for non-trivial migrations, 10-15% annual managed ops, the training budget, the "we forgot the SBC" moment. This estimator inflates those deliberately because it's better to over-estimate in a sales conversation than to come in 40% over.
Yes — the Webex Calling numbers approximate Collab Flex Calling. For Enterprise Agreements, discount 10-25%.
At 3-year TCO with hardware refresh — roughly flat vs cloud for 500-2000 users. Cloud wins on ops burden. On-prem wins on control and very large deployments.
~$260k over 3 years ($14/user/mo total TCO). Heavy on license, light on hardware.
~$420k over 3 years ($23/user/mo TCO). Heavy year-1 on hardware + pro services, lower ongoing.
