Carrier Strategy #

In order to make and receive external calls, each ~.Dimensions.~ customer must have a carrier strategy configured.

Depending on requirements, customers can be configured to use one of the following carrier types:

• ~.Dimensions.~
• Reseller
• Customer specific

The options available to configure will be different depending on the services that have been available to you. For information on using ~.Dimensions.~ or configuring a custom carrier specifically for a customer, please contact ~.Dimensions.~ support.

The trunk limit specifies how many trunks the customer has configured on their system, controlling how the maximum number of concurrent incoming/outgoing calls they can have.

note

Increasing the Trunk Limit will increase the trunk costs for the customer. Ensure that you understand the minimum contract terms in place before making changes.

For some customers it is essential that they can make outgoing calls, even if they are experiencing large incoming call volumes. ~.Dimensions.~ allows a subset of the trunk limit to be reserved for outgoing calls only. This works be effectively limiting the number of incoming calls. Once this limit has been reached, any new incoming call will receive a busy response.

For example, if a customer has 10 trunks and reserves 2 for outgoing, the system will restrict the number of concurrent incoming calls to 8.

warning

This feature ensures that incoming calls do not consume all available trunks. If there are outgoing calls in progress that are already consuming the reserved channels, it will not restrict incoming calls further.

The daily spend limit is designed to help limit fraud by removing the customer's ability to make outgoing calls once the daily spend limit has been breached. The limit can be updated on a customer by customer basis as required.

If a customer reaches the spend limit, you will be notified via email, allowing immediate action to take place.

warning

The daily spend limit applies only to completed calls and not calls in progress. The spend limit will need to be breached by a call before subsequent calls will be restricted by the system.

Changes to the carrier type or trunk limits can be requested at any time, but will only be implemented at the scheduled time provided. To allow infrastructure changes to be applied, a minimum of 24 hours is required between the carrier change request and the scheduled time.
