Incoming call fail to establish on PSTN number

While trying to configure direct line on my CUCM, PSTN line has been terminated and 7 digit number configured on my IP phone while Ringing from outside I can see the incoming call on my handset

However the issue is when the call is answered the call continues to ring unable to establish a call

 

Kindly please find the debug and running configuration which may help to provide real time problem.

 

Thanks in advance
