To create a BOQ for CUCM, you need to determine the required licenses, which depend on users or devices. You must identify the features the customer is seeking and whether it will run on the customer’s server or Cisco’s. Additionally, you’ll need to decide on the appropriate hardware based on the number of users and other factors.
This isn’t something that can simply be answered in a support community. Moreover, support communities are primarily for technical issues, not a place for BOQ assistance.
You should contact a local Cisco SE for help. If you’re a partner working with a Cisco distributor, you can reach out to the distributor for assistance. Alternatively, you could contact Cisco Partner Support, though I’m unsure if this option is still available to everyone.
