The Cisco Spare Telephone Handset Cable is a smart and cost-efficient way to replace a lost or broken Cisco telephone cable without needing to replace the entire IP phone. Compatible with Cisco 7800, 8800 and DX600 Series IP Phones, this phone cable connects to the handset and base unit with a standard RJ-9 port and has a coiled design with a custom end for concealed cable routing beneath the phone.
