It looks as if your PRI span is not configured correctly, The ISDN cause code 28 means: “invalid number format (address incomplete).”

Thank you , I think now I should focus more on reading about configuring PRI Span correctly & also should check for physical cable connectivity at PRI Line .Also I need to check if the dialplan is proper since It is giving error that “invalid number format (Address incomplete)”. Please correct me if my approch is wrong since I am very beginner and still learning configuring asterisk .

This would not be caused by a cable fault, unless you had multiple primary rate cables and plugged the wrong one in.

Thank you for your valuable inputs !
Then I would only focus on reading about configuring PRI Span correctly ,& also I am checking if the dialplan is proper since It is giving error that “invalid number format (Address incomplete)” May be my logic to develop a dialplan is wrong .

More likely to be that the dialplan is wrong and you are not sending the number in the correct format. That may be because you don’t undestand the service provider’s requirements.

If it is a DAHDI configuration error, you should look at the section of the sample configuration starting:

Dear Community ,
Than you very much for your kind support ! The issue was resolved after I created correct dial-plan for each number .

Sample corrected dialplan :

exten => 1488,1,Noop()
