Frequently Asked Questions
Is the Cisco CP-8841-K9 compatible with Webex Calling, BroadWorks, or Asterisk?
No. This unit ships with Cisco's Unified CM (Enterprise) firmware, which registers only to Cisco Unified Communications Manager (Call Manager). Webex Calling, BroadWorks, and third-party SIP platforms require the separate multiplatform (3PCC) firmware variant.
Does the Cisco 8841 support Wi-Fi and Bluetooth?
No. The 8841 is a wired-only desk phone with dual Gigabit Ethernet — it does not include Wi-Fi or Bluetooth radios.
Does the Cisco 8841 phone require a separate power adapter?
No. It supports Power over Ethernet (802.3af/at Class 2), so it can be powered directly through a PoE switch. An AC adapter is available separately if PoE isn't an option.
Is this unit new or refurbished?
This Cisco CP-8841-K9 is brand new, factory-sealed stock.
