Travamento de placa FXO.

Prezados, bom dia.

Tenho um cliente e frequentemente ele está reclamando que não está conseguindo fazer ligações, quando verifico as ligações estão travadas na placa FXO, o fabricante do PABX dele é um Alcatel, alguém consegue me ajudar, tem algum comando que eu coloque dentro da placa que faça ela de tempos em tempos reiniciar ou ficar monitorando a porta do PABX?

Tem alguma forma de analisar se o PABX não está mandando o sinal para o router desconectar a ligação sem alguém em loco, porque o site fica nos EUA.

Segue abaixo as configurações das placas:
