I was using this function to send and receive messages, but now I've come back, and it´s not working. It works to send them, but doesn´t get the inbound. This is the call ID from one case: 375f3294-7ddc-4051-bbb6-9289e4aa08b6 11:52:33 PM(+00:00.07)

Check the phone number is not assigned to another account' as part of your troubleshooting steps for this type of issue..
