We have installed the latest Pascom server, and no matter what we try, it wont provision our Grandstream GXP1625 endpoint. We tried to enable DHCP on server, then connecting the phone directly to the server. We tried to let the router give IP to the phone, plugged the phone into the LAN, then the PC into the pc port. Still no succes.
We factory resetted the phone as this tutorial says (https://www.pascom.net/doc/en/endpoints/grandstream/) but still no succes. Pascom documents says that the phone should be appear automatically under Devices, but its not even working, when im adding manually.
We tried to configure the phone itself, but still no succes.
Please give us some hint, what to look for, what to configure and where. Every PBX nowaday supports autoprovision. Should it work out-of-the-box?
Thanks in advance!
