How It Works

Cloudvox shuttles phone calls and SMS messages to and from your applications, exposing call control "building blocks" to your HTTP (JSON) or Asterisk (AGI, SIP) app.

Every account includes Web portal access for your whole team (Screenshots), unlimited apps with oodles of features (What You Get), killer docs (Code Samples & help.cloudvox.com), and Easy Setup. Be live with an SMS-capable phone number in a few minutes.

plain text protocol, or HTTP

any language, anywhere

HTTP

1. Call Control (JSON)→ serve JSON, control phone calls
2. Provisioning (REST)→ manage apps, SIP users, numbers

Asterisk

1. AGI (Asterisk Gateway Interface)→ presents incoming calls to your app
2. AMI (Asterisk Manager Interface)→ sends outgoing calls to Cloudvox

Which API is best for me?

Apps can be hosted on any Web or app server. They interact with Cloudvox via easy open-source libraries (like Adhearsion, Asterisk-Java, PHP-AGI, or simple JSON) and common protocols (HTTP or Asterisk).

Scripts send text commands, not call audio. A cable modem can be the "brains" for hundreds of calls.

Cloudvox converts the text commands into phone actions, like collecting keypad digits, generating spoken phrases, or creating conferences. Mix apps, traditional phones, and SIP phones to create your service.
