I have a question about the words "dialed"
Sometimes you call someone but who is dialing,the recording is "sorry, the number is dialed busy, please, redial later"or "sorry, the subscriber diadled is busy now,please,redial later"
The two sentencs the caller is doing now but of the word "dial"why add the "ed",why not is "dialing"?

I have a question about the words "dialed"
Sometimes you call someone but who is dialing,the recording is "sorry, the number is dialed busy, please, redial later"or "sorry, the subscriber  diadled is busy now,please,redial later" 
The two sentencs  the  caller is doing now but of the word "dial"why  add the "ed",why not is "dialing"?

Answer

I'm sorry, neither of those examples are correct.

"Sorry, the number you dialed is busy. Please redial later."

To dial a number means to enter the telephone number to begin a call. It is not the same as calling.  When you get a recorded message, you have already dialed the number and that action is completed.

Answer

Sorry, the number (or subscriber) you dialed is busy now, please redial later. 
[ it's a past tense here, you dailed just now, you are not dailing, if you are dailing, you would not hear the voice.]

Answer

Seriously, learn to type properly.

The number dialed IS busy. 
The number dialed = the number you have dialed
Hence the "ed".

Hello Fanny:

You are asking about a  third party's use of a word. The plain fact is, they can be using
the word in a grammatical error.   The fact is, the recorded person can say  dialing or dialed and either one can be correct, depending upon the context.

If you have other information,  you can  explain further perhaps?  --Warm Regards, Bruce
