There are three main reasons for this occurrence. This is what happens when you place an outbound call from your Exotel dashboard.
As soon as you click on the 'Call' button, Exotel places a call from your Exotel number to your number(the registered number). Once you pick up the call(Leg1 of the call), Exotel then triggers a call to the dialed number(Leg2 of the call). If all is well, the call should now be connected to the callee.
You may not get a call on your number for the following reasons:
1) Your number is switched off (doh!).
2) Your number is not reachable.
3) There is an operator-level connection problem (Eg: Calls from Airtel to Vodafone are failing).
4) Check your network connection.
5) Check if you have blocked the ExoPhone number in you mobile device.
Step 1: If your phone was on and if you had not got the call, please try restarting your phone.
Step 2: If a restart does not work then put the phone in the Airplane mode. Leave it on for about 30 seconds and turn it back off. This can do the trick. It will automatically reconnect to a closer mobile tower or a less busy mobile tower to provide stronger cellular connectivity. This will help you to figure out if there was a network issue at your end.
