I have a small test setup of FreePBX 14 with an S400 and a DB20N with 2 D10 handsets. I have the S400 contacts soft button using the REST-Contacts app and it works great for my needs. There doesn’t appear to be any way to configure the DB20\D10 handsets through the endpoint manager default config file.
I’ve logged into the DB20N and can see an option for “Central Directory” and it seems I can create and import a directory. However, I can’t find anything about the format of the import file. This isn’t ideal but would work for my setup. Does anyone have any help on the file format or another way to have contacts show on the D10s?
