I have a DX80 endpoint and I want to registration it to the CUCM ,the CUCM version is 8.6. After I manualy configure the phone type of DX80 , the
DX80 cannot registartion to the CUCM. I have already upgrade the firmware of DX80 on the CUCM and restart the TFTP service on the CUCM.
On the DX80 "About device" panel, when I check the Status message, I found that " HTTP No Error:SEP1C6A7AE12820.cnf.xml".
I cannot determine where is wrong with the message.
