Hi all. I am using 24 port 2960s POE cisco switches. I just implemented VOIP on the LAN only with a new ESI phone switch. I have had reports of 4 users throughout the LAN where their ESI 60 IP phones lose connectivity randomly, which causes their pc to lose connection as well.
Cisco sh logs, just show power granted after the phone reboots.
