I looking the following problem I have several clients, already I upgrade the phones with firmware 22.214.171.124 but, when I put in the GDMS the phone appear offline unless use the factory reset in the phone, thats the only method of the phone to appear online in the GDMS, I have more of 50 phones in several locations, please help.
Thank you for using GDMS platform! For some devices which are upgraded from an old firmware, the devices do not have the ACS URL to associate with GDMS platform. For such devices, users can factory reset, or put the ACS URL in TR-069 page manually to associate the devices with GDMS platform. We will consult a easier solution for those users who have a large amount of devices in the future. Thanks for your suggestion!
