    Cost-Effective SIP Phone for Business

    The SIP-T27P is a full featured SIP phone designed to deliver superb sound
    quality and uses standard encryption protocols to deliver secure remote
    provisioning. Offering a rich user experience and boasting a wide range of
    functionality, including SCA, BLF, 3-way conference and paperless labels, this
    Optima HD SIP phone is headset compatible and can be expanded using the
    EXP39 module.

    Key Features and Benefits
    HD Audio
    Enhanced Call Management
    Efficient Installation and Provisioning
    Highly Secure Transport and Interoperability

    Yealink Optima HD Voice is a combination of software and hardware design, as well as the
    implementation of wideband technology to maximise the acoustic performance. This,
    coupled with advanced acoustic clarity technology, such as full duplex, echo cancellation,
    adaptive jitter buffer etc. creates a crystal clear audio experience.

    The SIP-T27P incorporates productivity-enhancing features such as SCA, BLF List, call
    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
    YHS32 professional headset, and the EHS36 adaptor, which enables support of other
    headset brands.

    Integrated IEEE 802.3af Power-over-Ethernet allows centralised power management. The
    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
    providers to make use of the latest technology for enhanced network security. The phone
