I have pasted only relevant part of config , the question that i have is , i see that controller T1 0/0 , has "clock source Primary" , however i don't see the same command for other T1 controllers , is that ok or ISP missed to put that command for second Controller T 0/1
Any help will be appreciated

Please read this document on the meaning of that command:

There are 2 kinds of clock sources: internal and line (default=line). You can add the command "clock source line" to the second controller if you want.
Type "show controller t1" to view the current controller status and other related information.

Hi, best idea is to confirm the correct "clock source" with your ISP. The link might not work if you have different setting on either site.
You can refer to the url provided by ediortiz on what type of source and the command. Hope it solve your doubt.
