Cisco SPA122 VoIP Adapter

A Cisco SPA122 é o mais novo Adaptador de Telefone Analógico da Cisco. A substituição directa para o SPA2102 Cisco, o SPA122 proporciona a qualidade de voz e confiabilidade mesmo que os usuários têm vindo a esperar da Cisco ATAs.

Cisco SPA122 VoIP Adaptador geral

A Cisco SPA122 é um Adaptador de Telefone Analógico (ATA) com 2 FXS, 1 10/100 WAN e 1 portas 10/100 LAN. O SPA122 é uma voz baixa densidade inteligente sobre IP (VoIP) gateway que permite carrier-class residencial e de serviços empresariais de telefonia IP entregues através de banda larga ou conexões de alta velocidade à Internet para duas padrão RJ-11 telefones. A porta 10/100 LAN permite a conectividade de internet para ser estendido para um segundo dispositivo eliminando a necessidade de uma queda Ethernet segundo. As luzes LED indicam o estado de cada chamada e reagir aos usuários ações, como ligar / desligar do gancho e flash gancho.
