Les adaptateurs téléphoniques analogiques de la série Cisco ATA 190 vous permettent de transformer les appareils analogiques, tels que les téléphones, les télécopieurs et les systèmes de messagerie, en appareils IP. Les appareils de la série 190 sont des terminaux SIP (Session Initiation Protocol) gérés depuis votre réseau IP. Ils sont idéaux pour les clients disposant de réseaux d'entreprise, de petits bureaux et d'un système UCaaS depuis le cloud.

Qualité vocale
Cette gamme offre une qualité de voix supérieure, grâce à un système de traitement avancé, à l'annulation des échos, à la détection de l'activité vocale et à la réduction des bruits parasites.

Sécurité
La série ATA 190 prend en charge le cryptage le plus récent avec Transport Layer Security (TLS), Secure Hash Algorithm (SHA-2) et les nouvelles séries de chiffrement Secure Real-time Protocol (sRTP).
