I am new to FREEPBX and this VOIP phone thing. I have few CP-7821-K9= phones which I am trying to register. I set up the FREEPBX server. I am reading the wiki here https://wiki.freepbx.org/display/FPG/Configuring+Your+PBX#ConfiguringYourPBX-RegisteryourPBX
. It says I need the FreePBX CM EndPoint Manager. If I get that will the CP-7821 phones be registered with the server? I downloaded the firmware from Cisco website and there is no XMLDefault.cnf.xml. I am trying to update the firmware and TFTP server giving me error it can’t find XMLDefault.cnf.xml. Can someone please help here and point me to the right directions?
