A Client represents a user agent that can make and receive calls as well as send and receive text messages using the Restcomm Cloud. This means that you can configure any software or hardware VoIP phone with the Client Username and Password in order to register with Restcomm Cloud. Once you do that you will be able to do things like:
Call or text any Restcomm Number to trigger the associated Voice or SMS Application. Notice that you first need to setup the Application with the logic you want and associate it with a Restcomm Number. For more information please check here.
Call out to any PSTN number
Send SMS to any mobile number
Call or text any other registered Client
The Client can also be associated with a Restcomm Application, either in the form of Visual Designer Application or externally hosted. If that is the case then this application will be called no matter what digits the user of the VoIP phone dials
