Yealink Optima HD Voice is a combination of software and hardware design, as well as the

coupled with advanced acoustic clarity technology, such as full duplex, echo cancellation,
adaptive jitter buffer etc. creates a crystal clear audio experience.

forward, call transfer, and 3-way conferencing. Three pages of 8 soft keys are displayed
and can be programmed to support various features. The SIP-T27P supports the Yealink

SIP-T27P support the FTP, TFTP, HTTP, and HTTPS protocols for file provisioning and are
configured by default to use Trivial File Transfer Protocol (TFTP). In addition AES
encryption and XML configuration are also supported.

The SIP-T27P uses SIP over Transport Layer Security (TLS/SSL) enabling service
