Hi.
After making lots of inbound calls in i am not able to receive calls present event notifications in sandbox.
Before that the call status was Voice mail and the duration was 33 sec but now it show status Unknown and the duration is 6 sec in call logs.
The same thing happened with my first account and then i created another one which worked for sometime and then i had to create new account which also worked for some time and then i created another account which is working now and i am able to receive notifications and may be the same thing can happed again with the new account.
