Can NumberBarn or NumberGarage support my high-volume call-in campaign?

In this article:

Perhaps you're looking for a phone service that offers support for high-volume burst of calls much like a radio call-in contest. This is called a Choke Trunk or Choke Exchange and we do not support this functionality. Offering this using our service would potentially impair service for our other customers.

It's difficult to find providers that do support this. You might try ClearlyIP. If you know of other providers offering choke trunks, leave a comment and we will add this to our list.
