Grandstream Provisioning Failure
I am having a provisioning failure with our Grandstream 2604p. Firmware is 1.0.3.57 which show approved by zoom and provided by grandstream. I have tried the https url as well as the http url in the configuration guide. My DHCP is et to no and none, I see the phone downloading the file, but ultimately get a failed to download firmware... even though this is a configuration file and not firmware. I haven't been able to try then Web Interface option as I cannot find the SIP user ID or Authentication ID anywhere in the documents that is readable. Help
