Yealink SIP-T27P je napredni IP telefon koji zamenjuje prošli model SIP-T26P. SIP-T27P je telefon bogatih mogućnosti i sigurno će zadovoljiti najveći broj potreba zahtevnih poslovnih korisnika. U odnosu na prošli model, ima puno veći ekran na koji će stati mnogo više važnih informacija. Osim toga, povećan je broj SIP korisničkih naloga, te su dodati novi LED indikatori u dve boje. Novi dizajn DSS tastature je uklonio i potrebu za papirima na koje se pišu oznake pojedinih tastera - sve se prikazuje na ekranu, a 8 fizičkih tastera je moguće isprogramirati za 21 različitu funkciju (listanjem na tri stranice). Superioran zvuk sada osigurava Yealink Optima HD Voice tehnologija.
