Asterisk no Ubuntu 11.04

Boa tarde pessoal,

Estou precisando de uma ajuda de todos no asterisk.

Fiz a instalação do asterisk e ele está funcionando. fiz a configuração do mysql e tb está funcionando, porém eu não consigo acessar o FreePBX e muito meno o GUI. o meu apache funciona na porta 5000, pois a 8080 está sendo ocupada pelo asterisk sou novo no mundo do asterisk. Estou ainda "engatinhando" nos primeiros passos de configuração. somente consigo manusear o asterisk pelo shell e também pelo putty, quando estou no windows, pois eu tenho 2 computadores em rede.

eu tenho dois ramais internos:

1000 - admin
1001 - suporte

Eu consegui fazer o asterisk funcionar, porém estou tendo problemas para realizar chamadas entre ramais internos. eu fiz uns testes em épocas diferentes e tive 3 resultados diferentes:

As mensagens abaixo referem-se as tentativas de ligações aos ramais internos sem precisar acessar a telefonia comum.

Andei configurando canal para o dadhi e aparece esta mensagem abaixo:
Eu sei que para funcionar de uma maineira mais completa eu preciso ter uma placa E1, pois assim o dadhi funcionará, porém que quero fazer ele funcionar somente no sip e assim poder até mesmo ter uma comunicação interna com alguém diretamente.

alguém sabe o que está ocorrendo?

Quero muito colocar o meu asterisk para funcionar, pois tenho interesse em trabalhar na montagem e configuração deste servidor.

Alguém poderia me arrumar um modelo dos arquivos de configuração? pois já ví muitos tutoriais pela internet e até o presente momento não tive sucesso algum, ok?

Alguém pode me ajudar?

Obrigado pela ajuda.
