Asterisk connection with Panasonic T100 epbx

I am new to Asterisk. I am for the first time evaluating asterisk solution with our existing Panasonic T100 IP based epbx system.

I want to know is there any work done on this combination, if so then please provide the URL link. Else can anyone please guide me. I have installed Asterisk FreePBX Distro SNG7 on a VM. At present I have not attached any hardware. Can somebody guide me as what are infrastructure, I will need to configure this connection and how it can be done.

I have installed 2 softphones (X-lite and 3CX) and it is configure to make calls internally.

Thanks in advance.
