You need to be more specific. Does this affect all the phones? Does this mean that no phone can register with callmanager.

Can you ping CCM IP from the IP Phone subnet?

Is there a firewall between IP Phones and CCM?

Yes this affect all phones/extension, but randomly. This error occur when they are on call locally or outside number. The connection drop, and their phone is showing configuring IP status for about 10 seconds, and back to normal again. The phone can register with call manager again after that condition. Yes I can ping the CCM with no problem -> 1ms. The pc + ip phone is connected to cisco 3750g switch, 3 switch stack together. And I configured 2 vlan, voice and data. for voice vlan is giving ip by switch dhcp. but for data is giving ip by dhcp server on data subnet. Is it the ccm or the switch cause problem? Any suggestion?

Thank you for your help.

Where can I find UCM logs to check for registration events? Is it normal to have error 41 "temporary failure" on normal system ? Please advice. Thank you for your help.
