Re: Host Not found

Had this problem randomly and not too sure why it happens but the work around was to make a change in the phones profile... (add a letter to the description or somethinig) save it, reset it and then change it back, save it and reset the phone again and the phone would be rid of the dreaded "host not found"

Re: Host Not found

Hey, We have created 2 ccm group here, When registered the IP Phone to different C Cm its working perfectly, We are getting prob only in one CCM.

Re: Host Not found

How are the groups defined?

Ensure the Publisher is there in the group which is not working (assuming you are on the same cluster with different groups).

The reason being you can mention only one URL in the enterprise parameter per cluster.


Re: Host Not found

Are the phones remote?

Connected to a particular switch?

Any FW, TCP inspects between IP Phones and CUCM?

Which Phone model and firwmare?

Using IP address instead of hostname for URL?

Re: Host Not found

No remote

Its in the multipule switches

phone model is 7940/7960 FW:P00308000400

URL is working fine


Re: Host Not found

Try this, from IP Phone Service Configuration click on "Update Subscription". Well at least, it solved my problem with Host Not Found.

Re: Host Not found

Hi Sajish,

Take a look at the Directory URL in the CCM config and make sure that it is set as the CCM publisher IP address not CCM Publisher Name (DNS issue).

Directory URL can be found @

Enterprise Parameters Configuration>Phone URL Parameters>URL Directories >http://x.x.x.x/CCMCIP/xmldirectory.asp

Hope this helps!


Re: Host Not found


this URL is correct one only, i am suspecting we have to do something with Sql database, I think publisher and subscriber is not replicating SQL database...
