Nec ASPIRE ex no voice sip

[Saeidnec]

Hello, please help me. Our system has a 16-channel sip card. We have registered some grand stream gxp 2601 phones on the system and it works without any problems, but after about two hours, the phones remain registered and calls are made, but we do not send or receive sound. The problem will not be solved until the system is restarted once. The network is local. The phones are healthy and the system cards are also healthy. We have this problem in another system with sip trunk

Check your ethernet switches in case they are detecting UDP flood and are shutting it down.

Thank you for your answer. I also tested using a simple hub switch and the problem is the same.
And that I don't have the problem with the Grand Stream gxp1625 or Yalink t31 phones. I have it with some phones. And that the same problem occurs on the sip trunk.

Ya, really didn't know 3rd party SIP devices worked on the Aspire. I wish you well.
