DID Billing
Description
DIDs can be billed. DID billing is quite complex, as they have three types of rates. That means three prices are counted for one call. DID rates can be reached in the main DIDs window by clicking the 
Rates icon for the selected DID:
Incoming rate
For incoming calls, when the Incoming rate is greater than zero, the rate is paid to the system owner by the user who is dialing to that DID. It represents a profit for the system owner.
If the rate is less than zero, the price is paid TO the dialing user for the DID usage.
The dialing user is the user in MOR, and this rate applies only then when MOR recognizes the dialing user (by PIN/ANI).
Owner rate
For incoming calls, when the Owner rate is greater than zero, this rate is paid to the MOR system owner by the DID owner. This represents a profit for the system owner.
If the rate is less than zero, this price is paid TO the DID owner.
This rate is charged even if the local user dials another local user using DID with Owner Rate set.
DID usage is not allowed if this rate is > 0 and the DID owner does not have a large enough balance to cover call costs.
DID owner rate is not applied to the DID's owner - that is, the owner of the DID will be not charged when dialing his own DID.
Who is a DID's owner?
When a DID is assigned to User/Device, the owner is the User:
If a DID is assigned to a Dial Plan, then its Owner can be selected in the DIDs settings and any user can be considered as the 'owner' of the DID and can be billed at this rate when anybody dials this DID.
Select "Device" to see calls to this DID near this Device's calls:
Provider rate
For incoming calls when Provider rate is > 0 that means this rate is paid to system owner by Provider and it is profit for system owner.
Rate should be < 0 (less then zero) - then it means that this price is paid TO Provider for the DID usage.
