Analog extensions do not ring - Hipath 3550

[adrianoalves78]

I have a client that uses the Hipath 3550 where he is having the following problem, the analog DDR extensions when someone calls them internally or externally the devices do not ring, however if the extension receiving the call takes the handset off the hook it receives the call.
And a test was performed and the extensions only ring again when the Hipath 3550 is restarted, but after a few minutes the problem recurs.

I would like to know if someone has already answered a similar situation to help me solve it.

I'm waiting.

Thank you.

Tenho um cliente que utiliza o Hipath 3550 onde esta apresentando o seguinte problema, os ramais analogicos DDR quando alguem liga para eles interno ou externo os aparelhos não tocam, porem se o ramal que esta recebendo a chamada tirar o monofone do gancho o mesmo recebe a chamada.
E foi realizado teste e os ramais so voltam a ringar quando o Hipath 3550 é reiniciado, porem depois de alguns minutos o problema volta a ocorrer.

Gostaria de saber se alguem ja atendeu alguma situação parecida para me ajudar a resolver.

Fico no aguardo.

Obrigado.

Ring Voltage not coming from power supply - try changing out the power supply and re-test

Also seen a dodgy analogue card in a 3350 once where some extensions wouldn't ring. If you rebooted the system, the extension / ports affected would change...
