Hi,
In the documentation there are two options of configuring incoming call routing
To integrate incoming call routing, you must first get a phone number. Opsgenie offers two options to get the phone number;
-
Get a custom phone number from Twilio: Start a Twilio subscription and get your own, custom phone number. Usage-based fees will apply and will be billed directly by Twilio.
-
Have Opsgenie provide a phone number for you: Opsgenie will automatically provide you with a phone number. Additional usage-based costs may apply for phone numbers provided by Opsgenie. Trial customers can use the Opsgenie provided phone number for free until the end of their trial period.
How this is actually working in practice? If we choose a number provided by OpsGenie is it always a US based number? If you want a custom from a specific country outside of US what then? Does it mean that no matter what a Twilio account is required to proceed?
Have anyone configure this and have any guidance or feedback?
