I've UCM 6.1 with CCX 7. I am trying to configure IP Phone Agent Service (IPPA) and getting Host not found on the phones where this service has been subscribed. I am in DNS less environment, eternprise parameter and IP Phone service is pointing to the IP Address of Publisher.
I've Extension mobility login and Single buttong logout configured and working perfectly fine.
Not sure why Host not found in IPPA. Any comments how can I debug this issue?
Thanks in advance,
