What is the maximum number of contacts that Cisco Finesse supports in a phone book?

According to the Cisco Finesse Administration Guide, Release 12.0 (1), Finesse supports the following number of phone books:

10 global phone books

300 team phone books The system supports a total of 50,000 contacts. The total number of contacts per agent across all phone books is limited to 15001. This means that an agent can access up to 1500 contacts from the phone books that are assigned to them. If an agent has more than 1500 contacts, only the first 1500 will be loaded and displayed on the Finesse out of the box phone book gadget2. If a custom gadget is built using the Finesse API, it can show all the contacts by using the range feature of the API and grabbing 1500 increments3. References:
