Yealink SIP-T38G

 

SIP-T38G IP telefon je najnovija inovacija iz Yealinka za sve korisnike koji imaju zahtevne komunikacione potrebe. To je mudra investicija za budućnost jer telefon podržava Gigabit Ethernet, te omogućuje bezbolan prelaz na moderniju mrežnu infrastrukturu. Gigabitna brzina na dva mrežna priključka omogućuje fleksibilnije razmeštanje komunikacione opreme ali i niže troškove za kabliranje. Uz TFT ekran visoke rezolucije, T38G nudi sjajan prikaz informacija o sagovorniku, a korisnički interfejs je dizajniran za pregledno, jasno i intuitivno upravljanje svim funkcijama telefona. Osim toga, IP telefon Yealink SIP-T38G opremljen je TI Aries čipsetom HD slušalicom, HD zvučnikom i HD kodecima (G.722), nudi kvalitet zvuka bez premca i njegovo verno prenošenje. Dodatno, T38G IP telefon uključuje i sve standardne mogućnosti koje su već poznate na modelu Yealink T28P.
