CISCO CP-3905 Unified IP Phone 3900 Series SIP Handset Image 1

Cisco CP-3905 unified SIP phone for basic IP telephony deployments.

The Cisco CP-3905 is an entry-level unified SIP phone designed for basic voice communication requirements. This single-line IP phone features a compact form factor with a monochrome display, fixed function keys, and a standard 12-key dialpad, making it suitable for environments where straightforward telephony functionality is the primary requirement.

The CP-3905 is part of Cisco’s Unified IP Phone portfolio and operates on the Session Initiation Protocol (SIP). It is typically deployed in lobbies, common areas, break rooms, and other locations where users require simple call handling without advanced unified communications features.

This model represents Cisco’s legacy entry-level IP phone offering and has been discontinued in favour of newer platforms. However, it remains in active service across many existing Cisco Unified Communications Manager and third-party SIP deployments, making refurbished units a cost-effective option for spares or expansion of legacy systems.
