Greetings,

An odd issue release 4.80 7400 4) OAS cards around 175 IP sets. The system has been installed for 4 years Pri trunks multiple ip ranges for the phones. The system IP address is 192.168.88.5 about 5 phones in that network range have no audio on external calls just started happening about 2 weeks ago. Other phones in that range and the other ranges have no issues at all. They have rebooted the sets one grabbed a new IP address and worked fine after that. The other 4 still have the issue. Any thoughts? I was told they did make some network changes about the time the trouble started. MPS on the Samsung is off. The OAS port ranges are correct.

Thanks as always,
John
