IP Office 9.0 9608 Phones hanging off of a cisco POE switch. Every day at about 8:30 AM 4 phones will reboot with a "DHCP ACK Error" on the display of the phone. In System monitor under H323 status These phones have a URQError and a URQ Reason is TCPClose. A little back story this was a shoretell migration and this switch was orginally configrued for the shortell and the switch was cut in 1/2 the first 12 ports were reconfigured for a new vlan for the IP Office. Once the shoretell was decommissioned the 2nd 12 ports were set to the avaya vlan. Then these 4 phones were plugged into the newly configured ports.
For trouble shootitng we swapped a phone that was working (not rebooting at 8:30) with one that was. This morning both the phones rebooted. I was expecting the phone that had never rebooted to start rebooting and the phone that was rebooting to stop. I'm going to try to do a mute reset of the phone and see if that makes a difference. I don't maintain the cisco switch and have zero visibility to the configuration but something tells me that there is something missconfigured or maybe the interface connecting to the shoretell is still plugged in and may be causing the issue.
Anyone? i have read that if the port the dhcp server on is tagged with the voice vlan it could cause the dhcp ack error but that normally casuses the phone to not be able to register at all. In this case the ip office is the dhcp server and we don't have any issues with the other phones.
