Hi everyone. As a new member, I did a couple of research on this forum but couldn’t find anything helpfull. I have 2X ip phones GRP2615 I bought from a voip provider. They arrived pre-programmed. The after-sales service is just horrible and I found the options to be very limited so I decided to port my phone number to a new voip provider. I did a factory reset on the phones to enter the new parameters but still, the old config is always coming back. So I think there’s a config file calling for provisioning at boot up. Is there a way to erase or replace that file? Do I have to contact the former provider to ask them a key to remove those config files? Is there a special management tool or something in TFTP or SSH I can do?
After a factory reset, I successfully connected to the phone via WebUI on an isolated lan and changed some parameters but as soon as the phone got connected to the Wan, the old config was reloaded.
Thanks for your help and please consider I’m far from beeing a pro when answering.
