Twilio Registation Failed

[Jainesh]

Hi,
I am new to Twilio and 3CX. I am able to receive phone calls, however I am not able to dial out. Says "Called Failed", and looking at 3CX have SIP Error: Registration at Twilio has failed. Destination (sip:username%[email protected]:5060) is not reachable, DNS error resolving FQDN, or service is not available.

I talked to twilio and said they don't respond to sip registrations. Has anyone able to get this working.

And make sure you use the template. If you used their template there should be no registration as it is an IP authenticated trunk.

Hello @Jainesh

As @cobaltit hs mentioned Twilio should be setup as an IP based provider. Please follow the guide to correctly set the trunk up and let us know if you face any issues.
