Important
MPP Version - Not compatible with Cisco Unified Communications Manager (CUCM).

The 6800 Series is ideal for businesses that want to update their phone systems from traditional analog or digital-based systems to an IP communications system with supported multiplatform call control systems. The 6841 does not support PoE and is ideal for home offices or in non-PoE deployments. With 4 SIP registrations, the IP phone is still one of the smaller devices in the Cisco portfolio.
