Hey @stefke381, this could be a carrier issue, but it's hard to say. Do you see any failed inbound messages in your Twilio messaging logs, or evidence that the messages are arriving at Twilio at all?

He @ayyrickay , yes there are logs which show that message has been received successfuly from my phone number.

I see that the number is properly configured. Can you confirm that the functions we're expecting are indeed in your function services, and if so, are any messages being created in the Conversations service?

I'm guessing all of those things are happening, in which case the last part of the puzzle is to see if there's an issue with the WebSocket. If you open your Developer Tools, you may see whether the Conversations SDK is properly setting up/tearing down

Hi @ayyrickay!

I have the same problem with SMS receiving and Phone Call Receiving. We try to send SMS from another Twilio Phone Number and I see logs. It says Undelivered with Code failure 30008.
When I try to test incoming phone calls, dev-phone is ringing: reject button does not work, but when I press on accept button it fails immediately. Also I see in the Twilio logs (we have a flow that make the phone call) it says busy, but I press on accept button.

May you help me with it please?

@Siarhei-Asipenka-GY Hey, thanks for letting us know. That is very, very strange that it's happening for both calls and SMS. Are you using US phone numbers on both sides of this interaction?

[Siarhei-Asipenka-GY]

@ayyrickay Yes in both cases there was Twilio US phone number
