Hi All,
we have few new 7942 phones deployed and they are not registering.
we suspect that dhcp scope configured on cucm pub do not have any free ips to assign.
we need to know a way to confirm DHCP indeed is the issue.
Any suggestions will be very helpful.
Thank you

Hi,
I do not have any customers who run DHCP on CUCM servers but I would suggest that you look at using RTMT to collect log files from the DHCPMON service.
You could also check out the blog below:

The solution proposed is kind of neat but may not be something that you would be comfortable with.
Hope this helps

Hi All,
It turns out ITL file was the issue as these phones were registered to different cluster before
and DHCP had free addresses to assign.
DHCP DORA can be checked from RTMT syslog viewer-->system logs.
thank you all for the inputs.
