the sent phone number, the delivered time when SMS got
delivered, transaction ID, message-id, error code and sent
time. Thus, for any sent SMS, phone number 919xxxxxxxxxx,
and message HelloWorld, the server posts the following
data to your set URL script:
http://www.example.com/fetch_dlr.php?transId=81934341034091431&msgId=shdgMj33hk8&errorCode=1
&dlrTime=1505915325000&mobile=919xxxxxxxxxx
When you do not want to receive DLR, you can head

button to delete and system won't forward DLR thereafter.
