Good evening, for the past 4 days, I have been having trouble with one of my 3300's. New phones installed got the RCS error, until I expanded the DHCP scope by 5 more addresses. After that, I started to notice that some of the MAC addresses in the DHCP Lease Viewer were not phones, even after deleting the lease, the device would still hold onto that address making it unusable for a phone. This led into phones not being able to get DHCP addresses, we saw there was a data crossover and removed it. This solved our random MAC addresses appearing in the DHCP lease viewer, however some addresses still were unavailable, and even addresses that were not taken could not be used to static a phone. A new error started to appear in the DHCP lease viewer, "Server Reserved" and "IP in use" on the same line for multiple IP addresses. Deleting these has proved to be unhelpful as well.
Currently, I have 204 phones at this site, licenses for 209. I have 209 IP addresses reserved in my DHCP IP Address Range, however in the DHCP viewer I only have 174 IP addresses showing, and when I check to see which phones are out of service, I see anywhere between 4 to 9 phones. The numbers and situation is not making sense to me at all.
Does anyone have any suggestions for me or have encountered this problem before?
