SIP-T21P

Novi model Yealinka SIP-T21P dodatno podiže ljestvicu u konkurenciji "entry-level" IP telefona. Pri izradi su korišteni materijali visoke kvalitete, a najznačajnija novost u odnosu na prethodni model je dodatak velikog grafičkog zaslona razlučivosti 132 x 64 piksela koji sada istovremeno prikazuje puno više informacija na zaslonu. Ostale karakteristike su već poznate sa ranijih modela serije T2x: HD zvuk, dva 10/100 Mbps mrežna priključka, integrirani PoE. Telefon nudi dvije VoIP linije, te jednostavnu, fleksibilnu i sigurnu instalaciju. Dodatno, tu su i podrška za IPv6, Open VPN, redundantni server, SRTP/HTTPS/TLS i 802.1x.

Cjenovno vrlo prihvatljiv, a istovremeno vrlo bogat mogućnostima, SIP-T21P predstavlja idealno rješenje kako za manja, tako i za veća poslovna okruženja.
