How to order

CLASSOUND activation procedure consists of two steps:

1. Download and fill out the documents for your country
2. Fill out the form on WMP and upload all the required documents

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.

1. Go to WMP
2. Click Price list in the upper right-hand corner of the screen
3. Select the price list type (End User/ Gold/ Silver/ ...) and the format (EXCEL/ PDF)

Here is an example of a pricelist downloaded in PDF (please note that prices have been excluded on purpose from this example): 

In the document generated on WMP 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.

• 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.  

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. 

Pricelist FAQ

• How much does it cost for new international telephone numbers?

The CLASSOUND DIDs section lists the price of DIDs according to each country. Once the DID porting is complete, you’ll also find that inbound calls are free for the majority of the listed countries. 

Numbering ranges are available in units of 1, 10 or 100. 

For example: If your customer is a company with fewer than 100 users and needs 60 DIDs (numbering range) in Germany, they will pay the Monthly Flat Fee according to their company size, plus the monthly fee for those DIDs (6 packages of 10 DIDs). 

• Can I get also FreePhone DIDs?

Absolutely. 

This category follows the same pattern as the previous ones. In addition to the Monthly Flat fee, you’ll have to pay the FreePhone Monthly fee according to the customer’s country. Please note: the price per minute depends on the source of the call (fixed phones, mobile or pay phones).  

For example: If your customer is a company with 500 users and needs a FreePhone DID in Australia, they will pay the Monthly Flat Fee according to their company size, plus the monthly fee for their FreePhone DID and the price-per-minute fee corresponding to the source of the inbound call (fixed phone, mobile or pay phone). 

• How will I receive my invoice?

You will receive your invoice once per month. 

In the event that your agreement is suspended, the service will be suspended as well. However, we recommend that you close the deal at the end of the month, because any money you have already spent will not be refunded.

• How does migration work? 

Migrating has a reduced impact on your customer’s activities; when done through CLASSOUND, they will experience  no downtime. Outgoing calls will work via Classound from day 0 after the customer decides to switch, all without using temporary numbers as the outgoing caller ID. The customer will be able to immediately use their existing phone numbers. For incoming calls, the switch will occur automatically as soon as the previous operator releases the numbers to you. You’ll be informed in advance of the day and time that the porting will be done. On that date, no further action is required, as you can configure the incoming routing in advance.

• Is trunk configuration needed?

The trunk is built in, meaning you don’t have to configure it. 

DID configuration is done via WMP and then from WMS; you just need to indicate which Caller ID each user should use.

Configuration

CLASSOUND is a built-in trunk present on Wildix PBX. It is hardcoded and it is not visible in WMS on the Trunks page, but nevertheless, as each trunk it should have a Dialplan procedure associated to it. Dialplan procedure "classound" is present by default in WMS -> Dialplan -> Dialplan rules (or created automatically after upgrading the PBX to the supported WMS version). 

You should configure the incoming calls for the CLASSOUND trunk in this Dialplan context. Remember that certain Dialplan applications allow jumping to other Dialplan context, so you can configure the CLASSOUND Dialplan to jump to "main" or "users" procedure at some point, if needed.  
 

Managing calls 

Outgoing calls 

To route outgoing calls via CLASSOUND trunk, modify the Dialplan procedure used for managing outgoing calls (e.g. “users”). For example, add the Dialplan application "Dial the trunk" -> select "classound" from the list of trunks.

How to make sure that correct caller number is set for outgoing calls via CLASSOUND?

You have several options (in our example we will use the phone number +3904611715111):

• You can add this phone number as "Office number" in WMS -> Users, and it will be used as Caller Number when outgoing calls are placed from those users:
   

• You can set this phone number as Caller Number explicitly in your Dialplan that manages outgoing calls (by default, users) before routing the call through "classound" trunk:
  
  
  
  

• You can ask Wildix to set a default phone number for this PBX

E.g. you have purchased five phone numbers, you can ask Wildix to set one of these phone numbers as the default phone number for this PBX. This number will be used as Caller Number when outgoing calls are placed from users who have no "office number" configured, and in case Caller Number is not set in the Dialplan procedure that manages outgoing calls before routing calls via "classound" trunk.

Emergency calls

Universal Emergency services calls require the prior configuration. To do it, open a Customer Care ticket on WMP -> select CLASSOUND, details in Wildix Terms and Conditions.

If the service is not configured - calls will be answered with 503 Service Unavailable.

EU Emergency Services  

According to the initiative published by the European Commission, 112 emergency calls must met the following requirements:

• transmit information on caller location
• access for disabled people
• directing communications to the most appropriate Public Safety Answering Point (PSAP)

In order to ensure emergency calls, you need to provide geolocation data per each CLASSOUND DID, consult CLASSOUND EU (E112 ES) Emergency Services Compliance for details.

US/Canada 911 Emergency calls

According to the US Regulations, 911 calls are regulated by the 2 laws:

• Kari’s Law: requires direct 911 dialing, without any prefixes and also
• RAY BAUM'S Act: requires that every 911 call conveys a dispatchable location to get an emergency responder on site as quickly as possible.

The solution for the E911 compliance is available for every Wildix device (for non-fixed devices - starting from January 2022), for every system installed in the US that has CLASSOUND service enabled. No additional configuration is required, documentation CLASSOUND E911 Compliance.
