Enviando Voz

[rvannucci]

Bom dia galera,

Bom, ainda estou no projeto de voip e o pior que sozinho, portanto tenho apenas vc’s para recorrer.
Como está o projeto atualmente, eu pego a entrada do microfone e envio para um arquivo, sem fechar o arquivo eu tento manda-lo via RTP, mas me retorna vários erros.
Estou postando o meu código, e os erros:
