Outbound Calls Failing Amazon Chime

[cdnflt]

Just like the topic that JUST got locked, every time I make an outbound call, it automatically disconnects, I get a busy signal, and I get Temporarily Unavailable. The error I get is

• Cause: 400 Source number is not valid E.164 or anonymous value/INVITE from 3.80.16.123:5060

The number I use is prepended properly in my outbound rules and the log actually shows the number in E164 format, with a +1NXXNXXXXXX

I've checked the username and password in the credentials in Chime. Nothing is working.

Yes, I've gone through https://www.3cx.com/docs/amazon-chime-voice-connector-sip-trunk/ with a fine tooth comb.

If you are certain that the number you are sending is in the correct format, then it might be the caller ID you are sending, that they don't like.

Leejor is correct. The number you are dialing and the number you are dialing from must be in E164 format.
