UCCX not receiving external Calls

[ipo.peniel_rg]

Hi All,

I need assistance;

I have a 11.5 su3 CUCM and UCCX 12.0. I have configured UCCX all internal trigger is working. cti port registered.

I also have an ISDN PRI with 100 number range. the current setup is that the first number range is translated to the CUCM DN. The rest of the numbers in the range is unused.

Is it possible to use one of the numbers in the range and point it to the trigger? I have pointed one of the number range and pointed it to my CUCM extension and its working, however, when I replace my number with the UCCX trigger, its not working. Am i missing something? Please assist what to do.
