The SIP-T22P Professional IP Phone powered by YeaLink is a feature-rich cost effective solution for business applications. It uses the acclaimed TI Titan chipset, and offers a wealth of innovative features in a stylish and elegant design.
Yealink phones are fully interoperable for use on any open standard SIP IP-PBX platform. A wide range of Asterisk-based PBX's are supported, such as Fonality/Trixbox, Switchvox, Elastics and 3CX. Our own PBXnSIP and Epygi IP-PBX products have been extensively tested and optimised for use with the Yealink range of phones.
Advanced Provisioning via TFTP, FTP or HTTP and DHCP boot option 66, 43 provide for efficient deployment (Multicast PnP deployment is to be supported in a future firmware release - currently MAC address deployment is supported).
