We are using a stack of three N3048p switches. Out VOIP server is plugged into the stack and all VOIP handset traffic flows through these switches to get to the server.
After a software upgrade on our SwitchVox VOIP phone software, our VOIP handsets are having TCP connection issues with our VOIP server. The TCP connections are timing out so the handsets cannot obtain the latest configuration. They can successfully obtain an IP via DHCP and can obtain basic configuaration through UPD communications.
Port Fast and PVST are not enabled on the switches.
I even rebooted the switches in case there was as broadcast storm or traffic hung.
I am not an expert here so I am looking for someone that may have had a similar issue or places to look in our N3048 configuration.
Thanks
