*32 hours of voicemail storage is available by default across all user configurations. Any combination of personal mailboxes and general delivery mailboxes can be used.

**There are 20 simultaneous sessions available between IMAP Client and IMAP server. If all 20 sessions are used up, the remaining session requests will be rejected by the IMAP server. IMAP clients will automatically attempt to establish session with the server once some of the server ports are freed up. This does not limit the number of IMAP clients to 20.

Basic Call Center Capabilities

The Cisco UC 540 supports basic automatic call distribution (BACD) that can help answer outside calls with greetings and menus and allow callers to select the appropriate departments. BACD also provides managed call queues for calls that are waiting to be answered. Table 7 lists the BACD capabilities of the UC 540.

In addition to BACD, the Cisco UC 540 integrates with Cisco Unified Contact Center Express (UCCX). UCCX works with up to a maximum of 12 users (agents and supervisor combined) on the UC 540.

Voice Resource Utilization

The Cisco UC 540 includes four digital signal processors (DSPs) that enable digitized voice processing on the platform. The DSP resources available on the platform are used for various unified communications features, namely support of analog and digital VICs, prescheduled or ad hoc voice conference calls, and translation of digitized voice from a less complex codec (such as g711) to a more complex codec (such as g729) - typically used for deployments that use IP trunking (SIP or H.323) for PSTN access or multisite interconnection.

Each DSP can support 16 g711 channels or 8 g729 channels. This enables a total of 64 g711 channels on the Cisco UC 540. Table 8 indicates the DSP resource utilization based on the feature. Tables 9 and 10 show a few deployment scenarios based on the combination of these features.
