If you connect a SIP phone, Bitrix24 uses it for outgoing calls by default. You can switch the call between your phone, browser, and Bitrix24 Messenger at any time.
To route a call to your browser or Bitrix24 Messenger, start an outgoing call and click the blue phone icon.
To move the call back to your SIP phone, click the green phone icon.
Bitrix24 saves your choice. The next time you make a call, it uses the last selected option.
