You can connect your PBX using SIP connector, or you can select Marketplace solution and connect SIP PBX using REST API.

Differences between PBX connection options:

• Connect PBX using SIP connector:
  
  All the Bitrix24 Telephony options are available. Inbound calls are free, your telephony provider charges you for outgoing calls. You get charged monthly for using SIP connector. SIP connector needs to be purchased separately and is not related to Telephony balance. Make outgoing calls from your browser, desktop and mobile app.


• Connect PBX using REST API:
  
  Your PBX routes calls and handles voice traffic. Comparing to SIP connection, using REST API provides faster and better connection.

  If you connect your PBX using REST API, options listed below are not available:

  • Voice broadcasting in the CRM Marketing section;
  • Calls from a browser, desktop and mobile app;
  • Call transcription.

  By default, the following options are supported, but can be unavailable in a particular app or not supported by your provider:

  • Record calls;
  • Callback;
  • Assess the quality of service;
  • Selecting a particular phone number as a lead source in CRM.

How to connect PBX using REST API
