Uma ATA (Analog Telephone Adaptor) como o próprio nome já diz, é um adaptador que converte os sinais de telefonia analógica para digital, podendo o mesmo ser transmitido através da internet por meio de protocolos de voz (SIP, I-AX, MGCP e etc). Podendo converter uma linha de telefonia convencional como um tronco que poderá ser usado por alguns PABX virtuais, tais como Asterisk, FreePBX, Elastix, entre outros. Ou contrário, convertendo sinais de telefonia digital para ser usado por um telefone convencional. Será enviado: - Aparelho Ustart; - Fonte; - 1 cabo de telefone;
