Obrigado pela resposta
Também inicialmente me inclinei para que fosse tipo de problema mas infelizmente nada indica que o mesmo esteja acontecendo.
Pois quando tento uma config mais básica (dois CUCME a falar através do Asterisk o mesmo acontece)
para despiste tenho uma situação de lab (CUCME1) instalada com o seguinte cenário (real):
CUCME1 -----> ASTERISK -----> 2811 (SIP TUNNEL ENDPOINT) ---> CM 6.1
CUCME2 ------> ASTERISK
CUCME3 -------> ASTERISK
(IP Pub e IP priv)) (Ip Pub) (IP Pub e Ip Priv) (IP Priv)
O CUCME 1 está isolado apenas com dois telefones e uma conexão Internet.
Todos os tuneis são SIP inclusive entre o 2811 e o CM6.1 e Não há firewalls em nenhum percurso.
A ideia de utilizar este Asterisk como switch tem a vantagem dos DPs serem muito simples nos CME endpoints.
Alem disso há utilizadores no Asterisk também.
Ainda pensei que o problema estivesse relacionado com o CM 6.x estar numa gama de Ips privados (daí 0 2811 realizar o endpoint doSIP com um interface com Ip Publico e outro com IP Privado)
No entanto, há também falhas quando se liga dum CUCME para outro CUCME e estes têm Ip públicos num interface e os telefones numIP privado como se vê nas configurações)
O resultado obtido é o seguiinte:
Quando falha:

Aqui vemos que no áudio não foi nada recebido
Aproveito e envio a configuração do 2811 que serve de gateway SIP para o CM
