TheYealink SIP-T27G is a multifunctional SIP phone for business. Featuring excellent Optima HD audio quality, the SIP-T27G offers a full range of options for the user. The arrangement of programmable buttons on the device is laid out similarly to the older Yealink SIP-T29G model - four on each side of the display. In this case, one of the keys is used to turn OSD pages, which can set a total of 21 programmable values that are displayed directly on the phone's screen, eliminating the user from the paper carrier on the body of the device. The presence of the EXT port, which allows the connection of up to 6 expansion modules or the use of the Yealink EHS36 electronic micro-window for wireless headsets, makes the Yealink SIP-T27G an indispensable assistant in the work of the secretary, as well as in the work of the manager.
"Yealink HD Voice" is a combination of software and hardware design, and the introduction of wideband technology to maximize acoustic performance. Combined with advanced audio clarity technology such as full duplex, ECHA elimination, adaptive jitter buffer, etc., SIP-T27G provides clearer and more realistic voice communication.
SIP-T27G supports extensive productivity features such as XML browser, call parking, call capture, BLF, call forwarding, five-way conferencing, making it an ideal productivity tool for today's busy small and large offices.
