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. x-bees users can also send MMS messages (available only for US / Canadian and UK DIDs and Italy (in case of x-bees)). DIDs only).
