said by Arne Bolen:
Each DID has 10 channels as standard, allowing 10 concurrent incoming calls on the same number. Additional channels can be purchased if required.
Monthly fee for a US DID is $0.25.
This is somewhat misleading -- you need to purchase trunks (channels shared among all DIDs in a region or in the world) separately. Monthly cost of a channel varies from $7.75 to $22.00. See the Trunks worksheet in »www.voxbeam.com/static/voxbeam_d ··· orm.xlsx
