I am trying to connect several new 2135’s to GDMS but having no luck.
I have an active account on GDMS
I have added the phone serial and mac address to GDMS, which it correctly identifies as a GXP2135
I have updated the 2135 to the latest 11.3 firmware
I have gone to the Maintenance - TR-069 and input https://acs.gdms.cloud as the ACS URL.
There is no option on that page to enable or disable TR-069 (though there is two options, one for Periodic Inform Enable and one for Randomized TR069 Startup, both are disabled by default, though I have tried with enabled as well), so I presume it is always enabled now?
However the phone continues to be marked as offline in GDMS
Any suggestions please? Do I need any particular port forwarding or anything? It appears to just use standard ports 80 and 443. Do I need to put anything in the TR-069 username and password fields on the phones TR-069 page?
Thank you for any assistance.
