We have a few Sangoma S500 phones that have to be configured to use a non FreePBX SIP server. Everything works, and is easy to figure out, with the exception of details of what format to use for the XML address book that the phones can be set to use on the “Auto Provision” page.
I’ve searched but can’t find anything on what the phone expects this XML file to look like. Are there any details out there?
Thank you Tony, when I select Contacts in Phone Apps I get; This module does not currently have any settings.
Having mapped the Contacts App to a line key the display reads 'Contact Groups is not authorized in Phone Apps module for extension nnnn. I’ve checked my settings in User Manager, I guess I’m missing something?
