Cisco 8811 SIP Phone with Multiplatform Firmware - Refurbished

The Cisco 8811 3PCC IP Phone bridges enterprise-grade build quality with open-standard flexibility, arriving pre-loaded with Multiplatform Phone (MPP) firmware specifically designed for third-party hosted and cloud-based call control systems. Ideal for everyday office workers and business professionals, this reliable desk phone features a high-contrast grayscale display, wideband audio performance, and support for up to 10 distinct lines.

Combined with integrated dual-port gigabit Ethernet and robust enterprise security protocols, the Cisco 8811 3PCC delivers a dependable, high-quality communication endpoint for modern multiplatform office environments.

Advanced Performance and Multiplatform Flexibility

Engineered for businesses utilising open-standard cloud PBX platforms, the Cisco 8811 3PCC supports leading third-party call control environments including Asterisk (Release 1.8+), Broadsoft (Releases 19sp1, 20sp1, 21sp1), and Centile (Istra SP 9.2). The multiplatform firmware provides a robust feature set tailored for third-party integration, offering extensive telephony capabilities such as attended and blind call transfer, call parking and unparking, call forwarding, multi-party local conferencing, busy lamp field (BLF), and intercom support. Furthermore, auto-provisioning via TFTP, HTTP, and HTTPS ensures fast, scalable mass deployments for growing enterprise networks.

Comprehensive Connectivity and Audio Excellence

Designed to optimise desktop productivity, the device includes a high-resolution graphical grayscale display and fixed feature keys for messaging, directory, holding, transfer, and conference management. Audio performance is heavily optimised through wideband codecs (G.722, Opus, and iSAC) delivered across the handset, full-duplex speakerphone, and compatible headsets. Dedicated volume controls per audio path provide customised comfort for heavy phone users throughout the working day.

Network Reliability and Advanced Security

Network safety and enterprise integrity are maintained through rigorous security mechanisms. The phone supports Transport Layer Security (TLS) for signaling security, Secure Real-time Transport Protocol (SRTP) for media path encryption, and 802.1X network authentication. Encrypted configuration files and password-protected login options prevent unauthorised tampering, while dual-port gigabit Ethernet switches ensure your workstation network connection remains unhindered at full broadband speeds.
