Description

The IP Phone 8841 is a business-class 5-line desktop SIP phone from the Cisco IP Phone 8800 Series, built for knowledge workers and offices on hosted or open SIP UCaaS platforms. This 3PCC SKU ships with multiplatform phone firmware for Webex Calling, Webex Calling Carrier, Cisco BroadWorks and other approved SIP platforms, rather than Cisco Unified Communications Manager firmware.

It has five programmable line keys, a 5-inch 800 x 480 backlit WVGA colour display, a wideband handset and a full-duplex speakerphone. It supports up to 10 SIP line registrations with G.711, G.722, G.722.2, G.729ab, iLBC, iSAC and OPUS codecs. A built-in 2-port 10/100/1000 Ethernet switch lets a PC share the same network connection, and the phone is powered by IEEE 802.3af/802.3at PoE (Class 2). An RJ-9 analog headset port and an AUX port for electronic hookswitch control are provided.

The multiplatform firmware is certified for Webex Calling and Cisco BroadWorks, and is also certified for Centile, Metaswitch and Ribbon Kandy. Service-side subscriptions from your calling provider are separate.

FAQs

Q: Does this phone work with Cisco Unified Communications Manager?
A: No. This 3PCC SKU runs multiplatform phone firmware and is intended for Webex Calling, Cisco BroadWorks and other approved open SIP platforms, not Cisco Unified Communications Manager.

Q: Does it need a per-device licence?
A: No per-device licence is listed for the multiplatform firmware. Any subscription from your calling provider, such as Webex Calling or a BroadWorks or UCaaS service, is separate.

Q: How is the phone powered?
A: It is powered by IEEE 802.3af or 802.3at PoE (Class 2) with CDP and LLDP-PoE power negotiation. For non-PoE deployments, the optional Cisco IP Phone Power Cube 4 provides 48V DC from an AC outlet.

Q: Which calling platforms is it certified for?
A: The multiplatform firmware is certified for Webex Calling, Webex Calling Carrier and Cisco BroadWorks (releases 19sp1 to 23sp1), as well as Centile (Istra SP 9.2), Metaswitch (9.3) and Ribbon Kandy. Asterisk 1.8 and later is interoperability tested.

Q: Can a PC share the phone's network connection?
A: Yes. The built-in 2-port 10/100/1000 Ethernet switch lets a PC connect through the phone, so a single LAN cable serves both devices.
