Sippy Softswitch 2.1

Charging groups are used to charge DIDs with additional fees.


This feature enables an operator an ability to create multiple DID categories; for example, local DIDs will cost one assigned charged rate where toll-free DIDs can be charged at a higher price. When used, charging groups will affect call cost using surcharges in addition to Tariff rates. 

Charging groups are also useful for IVR applications. If used with IVR applications such as calling card or conferencing, it will result in a higher end user charge connecting with toll-free lines.

Starting from version 4.4 of the Sippy Softswitch, the DID cdrs are available from the web interface for the scenario when a Selling charging group is configured on DID.

Note: only the fees configured in Selling charging group are available in DID cdrs on web.

Parameter explanations for Charging groups:

  • Setup Fee: commission that is applied for account on stage of the DID assignment. In 4.x versions of Sippy, the "Setup Fee" and "Monthly Fee" duplicated each other and worked in the same manner, that did not make any sense for real-world billing. From 5.0 we changed the incorrect approach of this functionality. Thus now if you want to charge your account every billing cycle, you have to use the "Monthly Fee" option, because "Setup fee" is a one-time fee charged on the assignment of a DID to an account.
  • Monthly Fee: commission that is applied on monthly basis to the account that has the DID assigned
  • Free Seconds: amount of free seconds that are given to the caller after Interval 1 before first Interval N, between Interval 1 and first Interval N.
  • Grace Period: period in scope of Interval 1 that the caller won't be charged for the call. In case the call lasts longer then Grace Period, the regular charge of Interval 1 is applied to cover the Grace Period.
  • Connect Fee: fixed commission that is taken from the balance of an account after every single call made
  • Post Call Surcharge: extra charge that is applied to the cost of the call. It's extra % added to the final cost charged from account's balance.
