IP Phone Support
Using Cisco Unified Communications Manager Express, a maximum of 350 IP phones can be supported across a
choice of platforms. IP phone operation is similar to that for Cisco Unified Communications Manager, allowing for
ease of user training if you migrate to a Cisco Unified Communications Manager as you outgrow the Cisco Unified
Communications Manager Express Solution. Table 1 lists the maximum numbers of phones supported on each
platform with Cisco Unified Communications Manager Express 7.0.
