How to order
CLASSOUND activation procedure consists of two steps:

Please follow the instruction described here: CLASSOUND Activation Request.
CLASSOUND Terms of license
All services related to the same PBX have the same terms and expiration date.
E.g. if you have a PBX with yearly licenses, same terms are applied to CLASSOUND and/ or HWaaS ordered for this PBX. If you have a PBX with monthly licenses, same terms are applied to CLASSOUND and/ or HWaaS ordered for this PBX. This means, for example, you cannot have a monthly service (such as CLASSOUND or HWaaS) applied to a PBX which has yearly licenses.
Example: you activate a PBX with yearly licenses in May 2020: expiration will be in May 2021. You order CLASSOUND for that PBX in August 2020. In this case, CLASSOUND will expire the same date as the PBX: May 2021, and the cost will be prorated to the effective period (August 2020 - May 2021). The same rules apply to monthly and 5 year services. This means, the expiration date is always the same for the PBX and the services connected to that PBX.
Where to check the pricelist
Follow the steps:
Navigate to Pricing at the bottom of the page and click Price Book:
On the screen that pops up, choose the Product -> CLASSOUND and Price Book Type (Gold/ Silver/ Reseller) and click Next:
Look for the necessary option in the Search field. Or, if you want to download the entire list, choose the option Export to xlsx or Export to csv:
In the document generated in Salesforce Partner Community you find your price list covering monthly flat fees, DIDs, FreePhones and CallTermination for each of the covered countries.
Pricelist Guidelines
Below you will find the guidelines that explain how the price list work and how you can explain it to your customer. Let’s go through it and learn how the pricing works.
Monthly Flat Fee
The Monthly Flat Fee changes according to the size of your customer’s business and always includes 3000 minutes per user to countries listed under Call Termination Area 1. Once the 3000 minutes are used, a per-minute fee will be charged in accordance with the appropriate Areas table.
Note:
Call Termination Area 2 is available for the UAE and Saudi Arabia DIDs only and has a different price.
Call Termination Area 2 covers all countries included in the Call Termination Area 2 list (see details in the price list).
For DIDs in the UAE or Saudi Arabia, the special Flat rate, CLASSOUND-FLAT-CTA2, offers:
1000 minutes to all countries within CTA2
50 SMS to all countries within CTA2
Only CTA 1 or CTA 2 bundle can be activated on the PBX at a time. To switch from CTA 1 to CTA 2, open Customer Care Ticket.
The Monthly Flat Fee is a fixed cost that must be applied at any level and to any kind of contract
For example: “CLASSOUND-FLAT-1m,” the plan with the description “Flat CLASSOUND 3000 min per user for 1 month (Users 1-5),” is dedicated to businesses with up to 5 users. This means that a customer with 4 users will pay the listed price multiplied by 4 and will get 12000 minutes of calls to countries listed under Call Termination Area 1.
Notes:
These 3000 minutes are not divided among other users.
The number of users can be checked in Salesforce Partner Community -> choose the necessary Opportunity-> Fast Change Order, where you can view PBX with the activated service and see CLASSOUND FLAT. The calculation is based on the overall number of user licenses including Essential, Business or Premium.
Call Termination Areas 2-6 is charged per second starting from the 1st second.
CLASSOUND allows your customer to make outbound calls even without porting DIDs.
In this case, once the 3000-minute package included with the Monthly Flat Fee is exhausted, customers will be charged for calls in accordance with the Call Termination price list and the applicable Areas section.
