L’adattatore per telefono analogico multipiattaforma Cisco ATA 192 trasforma i tradizionali dispositivi di comunicazione telefonica, telefoni, fax e cercapersone in dispositivi IP per una maggiore convenienza. I clienti possono trarre vantaggio dalle applicazioni di telefonia IP collegando i propri dispositivi analogici agli adattatori per telefoni analogici Cisco.

ATA 191 è la soluzione d’elezione per soddisfare le esigenze dei clienti che si connettono dal cloud a reti aziendali, piccoli uffici o comunicazioni unificate. Ha due porte FXS standard che possono essere configurate indipendentemente come due registrazioni SIP (Session Initiation Protocol). Ha anche due porte 100BASE-T con un router integrato ad alte prestazioni per estendere la connettività della rete locale.

ATA 192 è progettato per funzionare con sistemi di controllo delle chiamate di terze parti e non funziona con i sistemi di controllo delle chiamate di Cisco.

Qualità vocale
Offre una qualità della voce chiara e naturale grazie alla preelaborazione avanzata, ad una cancellazione dell’eco ad alte prestazioni, al rilevamento delle attività vocali e alla generazione del rumore di comfort

Sicurezza
La serie ATA 190 supporta la crittografia più recente con Transport Layer Security (TLS), Secure Hash Algorithm (SHA-2) e le nuove suite cifrate Secure Real-time Protocol (sRTP).

2 profili SIP tramite 2 porte
Router
IPv6 Ready
G.711 fax pass through e T.38 FoIP
