Frequently Asked Questions
Is the Cisco CP-8861-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 8861 support Wi-Fi?
Yes. It supports dual-band 802.11a/b/g/n/ac Wi-Fi (2.4 GHz and 5 GHz) in addition to its built-in Gigabit Ethernet switch, so it can be deployed wirelessly in locations where running network cable isn't practical.
What's the difference between the 8861 and the 8851?
The 8861 adds dual-band Wi-Fi and a second USB port with up to 2.1A charging, plus support for up to three Key Expansion Modules (113 lines/features), versus the 8851's Bluetooth-only wireless connectivity, single USB port, and support for up to two Key Expansion Modules (66 lines).
Does the Cisco 8861 phone require a separate power adapter?
No. It supports Power over Ethernet (802.3af/at, Class 4), 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-8861-K9 is brand new, factory-sealed stock.
