[AsteriskBrasil] Problemas de Eco e Voz cortada

[Rodrigo Gonzalez de Souza]

Olá a todos,

Algumas ligações estão chegando com eco (só pra quem está dentro da
empresa), e outras, pra quem é de fora da empresa, recebe nossa ligação como
se a comunicação estivesse falhando "com a voz cortando".

Tenho um servidor com mais de 200 ramais SIP, uma placa **Digium TE410P com
módulo de cancelamento de eco, dois E1 chegando nessa placa.
Todos os aparelhos são telefones VOIP usando codec G.711Mu. Estão numa rede
físicamente separada da rede de dados. Não tenho nenhum tronco SIP ou IAX.

Verifiquei o aterramento, a operadora testou os links E1, verifiquei consumo
de processamento e memória do servidor.
