Review on Enhance Your Communication with the Grandstream HT801 Single-Port Analog Telephone Adapter by Heather Hernandez

In all the tutorials I found on this the admin password is "admin" but it doesn't work. I found another password but it doesn't work either. The user account password 1234 works and allows you to access the device to view its configuration, but you cannot make any changes. We found out on the Internet that these devices can be ordered with custom firmware, which for provider companies has its own administrator password. So I'm wondering if the ones supplied by Revain have custom firmware. I was planning to use this with 3CX as it is fully supported by the 3CX GUI but I am unable to set up the device as no changes are saved. I think I'm going back to Patton M-ATA.
