The Abilis permits to pilot Input and Output also making phone calls. For that we use a LUA script joined to DISA resource that allows to open Gate#1 connected to Digital Output 1 verifying the calling number.

	Note
	This advanced configuration normally is realized by Second Level Abilis support. Bellow are reported only the resource configurations and a short logical description.

1 - The Abilis verify to receive a call to the called number 0213456789 from the calling numbers recognized in list CallingOK, in this case is sent a call to the DISA Service with called Number 91.

2- The DISA resource, configured like below, receive the call with called number 91. The DISA SERVICE:entryphone refuse the call but recognized the number that is motorized by LUA Script.

3- The script ephone-cd.lua verify the last digit of the called number and pilot the corresponding Digital Output. In this example the called number is 91 then the driven Digital Output is D-OUT: 1.
