Destruição de diálogo do asterisco no tempo limite de transferência assistido

Question

Passos para replicar:

1. Alice recebe uma chamada de Eva (seja de uma linha externa ou de outra extensão, não importa).
2. Alice transfere a atenção para Bob e desliga antes de Bob responder.
3. Bob não atende o telefone dele.
4. Após $ {ATXFERNOANSWERTIMEOUT} segundos, em vez de dizer algo como -- Nobody picked up in 30000 ms e passar para o próximo comando na caixa de diálogo dialplan é autodestrutado e toda a conversa termina sem nunca passar pelas etapas do plano de discagem.

log:
