patton 4316 with panasonic KX-TDA600

[Raghed Idris]

i am trying to integrate panasonic KX TDA600 to 3cx using patton 4316
first i added the patton 4316 as gateway analogue FXO but it only allows 4 ports although it's 16 port.
i followed the steps of adding FXO 4112 and i connected the fx0/0 port of patton to anlogue extension from pansonic pbx.

please advise about next steps
