Configuring busy settings

Last updated:

The Advanced Telephony Connector allows making outgoing phone calls and receiving incoming phone calls via the Circuit application using your work phone number.

When you have set your incoming calls to go through the default routing sequence, you can further specify how new incoming calls will be treated while you are busy on a phone call. You can have these calls continue default routing, get a busy signal, go to your voicemail or alternative number, if you have specified one.

  1. Navigate to Settings > Telephony.
  2. Then:
    • On the web client and Desktop App, locate the Busy setting section.

    • On the iOS mobile client, tap Busy settings.

    • On the Android mobile client, tap Busy settings and, then, Send incoming calls to.


    The Busy settings section is visible when the Default routing is selected as the preferred option for Incoming call routing.

  3. Specify how new incoming calls will be treated while you are busy on a phone call by choosing one of the following options:
    • Default routing

      New incoming calls will continue default routing.

    • Busy signal

      New incoming calls will get a busy signal.

    • Alternative number

      New incoming calls will go to your alternative number.

    • Voicemail.

      New incoming calls will go to voicemail.


    The option to route your incoming calls directly to your alternative device is only available if you have specified an alternative number.


    The option to go to voicemail requires your telephony administrator to enable voicemail on your company’s phone system.


    The voicemail number is administered on your voice platform (OpenScape Voice or OpenScape 4000) when the ATC is configured for you.
