I am testing out VitalPBX as a replacement for our old Asterisk/Another PBX system. I have a number of Grandstream GXP-2000 phones that I need to provision. I’m trying to follow the manual in order to request/create a new template, but the manual appears to be for Version 3 of VitalPBX and I have installed Version 4. How do I go about getting provisioning support for Grandstream GXP-2000 phones so that I can evaluate whether VitalPBX will work for us?
