This was an issue in phone firmware as it  turns out: This is the BugID that is the most likely cause of the issues: 78xx Cannot join VLAN if broadcast over 30kbps CSCun23612 Description Symptom: 78xx Devices are not able to process CDP response to gain VLAN knowledge from switch when large amount of broadcasts (30kbps / approx 40 to 60 pps) on VLAN/Subnet are occurring. The phone looks like it will still follow through with DHCP requests but will not accept the offered DHCP address due to the phone not knowing the VLAN structure. ** Issue does not occur when same amount of traffic is sent directly to the phone; only when it is broadcast traffic. Conditions: 78xx on a switch port with a VLAN with a large amount of broadcasts occurring in subnet. Workaround: Reduce Broadcast traffic below 30kbps and reboot phone or Remove VLAN from Switch port that has the high Broadcast traffic.     Confirmed by only have access vlan on the switch port and phone registered and upgraded all perfectly fine.   Neil ...

Hello, Also have a customer with this issue, yet on Unity Connection not CUCM. Do we think this bug could hit them both? Also, How do you shrink the tftp areas you are describing? And does it make any difference to a restore? or even shrink size of drf files & time? Thanks, Neil ... View more
