Also, you can configure how calls are processed if Bitrix24 user does not answer :

• Continue call processing - calls will be processed according to the current inbound calls routing settings.

  Don't forget to specify the employee's mobile number on his/her profile page. The number must be specified in international format.
• Leave voicemail message - a client can leave a voicemail message.

  For the correct processing of the extension number in the number settings, the playback of the greeting (Hold music > Greeting) should be enabled.

  If the voice menu (IVR) is enabled, the extension from the greeting melody is processed first, and then the voice menu is processed.

  Direct incoming call with an extension to a Bitrix24 employee is not supported. An extension can be entered only after the greeting melody or in the IVR menu.

  For a direct outgoing call, an extension number is separated from the main number by the following characters: ; or #.

If the responsible person doesn't answer the call within 30 seconds, you can select one of the actions: forward to queue group, forward to mobile or leave a voicemail message.

You can specify a Prefix for calls via this number to make an outgoing call from this number by dialing the specified prefix on your phone.

Prefix selection tips

You can use combinations of symbols and numbers as prefixes. Use only those symbols that you have on the phone's dial pad. We don't recommend to use + in prefix as it may be recognized as a country code.

• We recommend to use * or # in prefixes. For example, *123*, #123#, *123# or #123*.

  So to make an outbound call using the selected connetion, an employee needs to dial: *123*destination_phone_number (for example, *123*12125599676).

• If you use a combination of numbers as a prefix, make sure that it's not a country code. For example, you can use: 801, 802, 803, etc.

  So to make an outbound call using the selected connection, an employee needs to dial: 802destination_phone_number (for example, 80212125599676).

Also, you can specify Employees allowed to make calls using this phone number in this section.

When a call is redirected to the backup phone number, you get charged according to the outgoing calls price list for the selected telephony connection option.

By default, a call will be forwarded inside a current connection. You can select another available connection to forward a call.
