IP Phones 521s can´t register, on the display shows " SPCP Register Token Rejected" but if a configure this phones as a 524g phone, it works. but in this case the Pc port,is disabled.
Plus ,trying to acces "Phone load Management on CCA" this window appears: "Unable to read information from the device. Either phone load directory is missing or communication to the device failed" so i can´t see the phone loads.
Does the pc port work if the phone isn't connected to the UC? The port should have worked regardless of registration status with the UC. If not working, it sounds like a hardware failure with that port.
