[AsteriskBrasil] Controle de BANDA

Segunda Setembro 27 15:46:09 BRT 2010

Se tu usa o link exclusivamente no server, não faz sentido usar esse script
de QoS;
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
