Have you allowed the required country codes - Settings - Security - Allowed Country Codes

Make sure 'Disable External Calls' is unticked under Options for the extension

Check the 3CX activity log to see what 3CX is doing and any responses back the sip provider

I have allowed the country code and the activity log said '403 forbidden' like this

Enable back the E164 but just make a clean outbound rule, without any restriction..

The Cause said :
You are getting 403 Forbidden responses to your INVITE requests

There is an ACL on your trunk and you are sending us INVITE requests from an IP address not on that ACL.

But i have added thoes IP addresss to ACLs

I will try is now

I will try is now

The new error has nothing to do with E164 settings and outbound rules.

Not sure how to resolve the new issue, hopefully someone will help you - maybe worth creating a new thread for the forbidden error

Make sure to do this!

ACL on Twilio is really important. Make sure your IP is configured and all is linked together on Twilio.

As above, ensure your PBX public IP is in the access control list of Twilio.

It is also listed on our guide here: https://www.3cx.com/docs/twilio-elastic-sip-trunking/#h.nwjgvw1hnwua

Is twillio making some restrictions on call destination? perhaps 403 come because destination is forbidden on provider side.

Have the case this morning with my provider, everything was allowed on PBX side but when i tried to call from France to netherlands destination was blocked by SIP provider for security reasons against hacking attempts. So i need to ask them to open destination to avoid 403
