Introduction

The feature allows exchanging SMS messages with external users via CLASSOUND service. PBX users can initiate communication directly from Collaboration / x-bees and also use their mobile apps for further SMS exchange. For this purpose, you need to have activated CLASSOUND DID on your PBX and assign it as Office number for those PBX users / SMS number for Call Group in case of x-bees who need exchanging SMS messages with their customers. External users can send messages to a company number published on a website (available only for US/ Canadian and UK DIDs and Italy (in case of x-bees))x-bees users can also send MMS messages (currently available for US / Canadian DIDs only).

Note

Note: By default, Wildix provides a package of 200 SMS per each user per month. Once the package is used, a fee will be charged for each sent SMS. The same fee as for calls is applied (CallTerminationArea_1). You can check the fee on WMP -> Price list -> CLASSOUND.


Note

Note: Starting from December 2023, 2-way SMS is available for Belgium, Denmark, Czech Republic, Italy, Lithuania, Poland, Singapore, Sweden. Currently, to order 2-way SMS DIDs for the mentioned countries, you need to open a Customer Care ticket.

Note

Note:

For some countries, it is necessary to register your sender

  • For some countries, it is necessary to register your sender ID. As a local regulator, it can block SMS sender IDs that are not registered. The list of countries is listed here ETA per Country (1).
    To register ID, make a request to the CLASSOUND support team.
  • For Italy, destinations don't use Sender IDs with Italian given names (such as Federica, Marco, Francesca): Italy has received a lot of phishing traffic in the past using this type of Sender IDs, which is why these messages were filtered as probable phishing attempts. It is not recommended to use this type of Sender IDs.

Prerequisites

  • Activated CLASSOUND 

  • Min. license type: UC-Business (only users with UC-Business and UC-Premium licenses can send and receive SMS)
  • CLASSOUND DID configured as Office number for those users who need to exchange SMS messages via CLASSOUND

...

  1. Enter/ select a phone number in Collaboration Search field -> click 2 Way SMS: [number].


  2. A group chat is automatically created, which includes the PBX user who is sending the SMS and the receiver. You can manage it as an ordinary group chat: change the title, add/ remove participants (you can find details in Collaboration User Guide).

    Note

    Note: It is not possible to attach files in two-way SMS chats in Collaboration.


When an external user sends an SMS message to the company DID number (activated via CLASSOUND service), a group chat is automatically created, too. It includes PBX users who matched according to the Dialplan procedure or those who match licenses and Office number requirements; the conference title coincides a DID number from which messages are sent:

...

  • Use CLASSOUND DID as a called number 
  • Add Call group Dialplan application

    Note

    Note: All the Call group members should be static and assigned a UC-Business license (or higher) and have CLASSOUND DID as Office number.

Note

You can create a separate Dialplan procedure for managing SMS exchange, but messages can be delivered even without it, because initially the system finds the full match for the CLASSOUND DID (including +) and static Call group members with at least UC-Business license. If at least one user is found, a group chat is automatically created. Otherwise, the system searches users in the LDAP who have the CLASSOUND DID specified as their Office number.
