Unified IP Phone 7841

The EVESKY CP-7841-K9 is a wired VoIP handset built for small to large businesses that need a reliable desk phone. It provides four programmable line keys and SIP registration for unified communications. A 3.5-inch backlit display gives clear visibility for call details and directory access.

Simple desk deployment

The phone connects through two 10/100/1000 Ethernet ports, allowing a single cable run to serve both the handset and a downstream PC. Power is typically supplied over Ethernet, so no separate adapter is required. The main installation issue occurs when the switch port does not deliver PoE or the VLAN is misconfigured, leaving the device without power or network access.

Check your network before ordering

Verify that your infrastructure supports Power over Ethernet on the intended switch ports. Confirm the voice VLAN is configured and that SIP signalling is permitted through any firewalls. Ensure the cabling run meets the 10/100/1000 specification for the full distance to the desk.
