Se tu usa o link exclusivamente no server, não faz sentido usar esse script de QoS;<br>Explique melhor o cenário. Se usa ATA, qual codec, se o problema ocorre somente via vono ou entre ramais tb, se tem simultaneas e quantas.. etc etc<br>

<p class="MsoNormal">Olá Comunidade,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"> - Eu estava com problemas de RUIDOS no meu
VOIP, eu estou usando VONO e VIRTUA para a comunicação, resolvi comprar um link
de 12MB por 700K e usar este exclusivo para meu Server VOIP, porém continuo com
problemas de ruídos e picote na ligação, quando faço o teste de velocidade este
se apresenta PERFEITO, sempre com a velocidade de 12MB x 700K, não tenho nenhum
gargalo na rede física LOCAL, porém mesmo assim resolvi copiar um script de QoS
que consegui no asteriskguru, e adaptei-o, porém acho que as vezes o problema
pode estar nele, e preciso da ajuda de vocês (Minha rede: <a href="http://192.168.0.0/24" target="_blank">192.168.0.0/24</a>).</p>
