Cant use dev-phone with region ie1

[mstuercke]

Hi, I'm unable to use the dev-phone with the region ie1

Steps to reproduce:

1. create an account in ie1
2. create a profile twilio profiles:create <account-sid> --region=dublin.ie1
3. use profile twilio profiles:use <profile-name>
4. start dev-phone twilio dev-phone --profile <profile-name>

Outcome: Error: ENOTFOUND forsync.dublin.ie1.twilio.com

Additional information

• Using --region=ie1 with profiles:create does not work
• I've also tried using environment variables TWILIO_REGION=ie1 and TWILIO_EDGE=dublin does not work as well
