If you have an ACD with that phone number, you cant have a phone with that number and also the ATT Console can't forward just that 1 number anyway. it would forward all calls.
When your explaining something you need to be clear in what your saying.
"I have created an ACD in LD 23 then Name it in LD 95. When I call it from a phone inside it works. If I cann from the outside, it only give me the number."
If I call from the inside it works. What do you mean it works?
If I call from the outside it only gives me the number. What Number?
