Corex360 Cloud PBX is the cloud telephony module that makes calls from the browser over a WebRTC extension assigned to each staff member and ties the call history to the customer card of the calling number. With the switch on, the number you dial gets an info SMS that introduces you; PBX numbers and extensions are set up on the module's own screens. Looking for a carrier for a line or number? This page covers the module that writes the call to the customer card, not the line itself. The NetGSM integration for PBX and SMS is on the [NetGSM page](https://www.corex360.com/en/integrations/netgsm).

Short answer Corex360 Cloud PBX is the cloud telephony module that makes a business's calls from the [Call Center](https://www.corex360.com/en/blog/call-centre-vs-pbx) window in the browser, files incoming and outgoing calls, with their duration, on the customer card of the calling number, and runs on the same core as CRM (customer relationship management). Calls, messages, and email link to the same person. PBX numbers, extensions and PBX staff are set up on the module's own screens. ### Who it is for - Sales teams that call customers and call them back - Teams that talk to the same customer by phone and on WhatsApp - Managers who want to see missed calls in one list - Businesses that do not want to keep a separate call log ### What it does not do - It does not make calls itself; a person on the team makes them. - It does not send the info SMS while the switch is off; the switch is the user's. - It is not a separate product; it is a module of the Corex360 core. ### What this page does not promise Line and number allocation, carrier compatibility, call audio recording, a voice menu, and a screen that pops up on a call are not among the things promised for the PBX module. ### Topics for the demo - How missed-call follow-up is set up. - Line and number allocation, carrier compatibility. - The hardware scope. - The content of the info SMS. ### Setup Corex360 runs in two ways: in a company-specific space on Corex360 Cloud or on [your own server](https://www.corex360.com/en/solutions/on-your-own-server); the choice is written into the agreement. Product demos are given live and online. ### How pricing is set No list price is published on the site; pricing comes in a written quote after the demo.

The company's PBX numbers and a new PBX are set up on their own screen, and a new extension opens from the quick-create menu and is given to a user. On the PBX and SMS side it works with NetGSM. ### PBX numbers The company's PBX numbers are listed on their own screen, and a new PBX is set up from there too. ### New extension A new extension is created from the quick-create menu and given to a staff member; PBX staff are followed on a separate screen. ### Past calls Past calls are listed on a screen of their own, apart from the Call Center window. ### NetGSM integration The PBX and SMS side runs integrated with NetGSM. PBX CRM integration ## How is the call written to the customer card? The Corex360 PBX is a module on the same core as CRM (customer relationship management) in the product menu. The [call log](https://www.corex360.com/en/glossary/call-log) glossary entry explains what call history is. A call from a number is tied to that customer's card; incoming and outgoing calls sit on the person's card with their duration, and phone calls, chats and email meet on the same person's record. ### The same person is recognized The caller's call ties to that customer card. ### Call history on the card Incoming and outgoing calls, with their duration, sit on the contact card; the Call Center and Customers open as tabs in the same window. The card is described on the [CRM](https://www.corex360.com/en/modules/crm) page. ### Contact tied to the same person Phone calls, chats, and email meet on the same person's record. The chat side is on the [WhatsApp CRM](https://www.corex360.com/en/modules/messaging) page. Workflow ## How does a ringing phone reach the customer card? In Corex360 PBX the road from a ringing phone to the customer card runs on one card; no separate call log is kept. A user connects to their own extension with the Connect button in the Call Center window, and the caller's call is written to the customer card with its duration. With the switch on, the dialled number gets an info SMS; a missed call stays in the history and a team member takes on the call back. - 01 **The PBX connects** Staff connect to their own extension with the Connect button in the Call Center window; each call ties to the caller's customer card. - 02 **The call is written to the card** The call is filed on the caller's customer card, with its duration. - 03 **The info SMS goes out** With the switch on, the number you dial gets an info SMS that introduces you; the call history stays on the same card. - 04 **Missed calls in the list** A missed call stays in the call history; a person on the team calls back. Integration ## What does the PBX connect to? The Corex360 PBX connects to where a call runs and where it is written. The call runs in the browser on the WebRTC extension assigned to the user, and the call history sits on the caller's CRM (customer relationship management) card. The same person's WhatsApp and Instagram chats are in the Messaging module; with the switch on, the info SMS to the dialled number goes out through the NetGSM integration. - **Browser** Calls run in the browser over the WebRTC extension assigned to the staff member. - **CRM customer card** The call history sits on the card of the calling number.
