Phone calls conversation

Last updated:

The Circuit Telephony Connector allows users to establish phone calls between the Circuit client and legacy telephony devices, connected to the public switched telephony network (PSTN) via the voice platform.

  • When using the UTC or the OpenScape Business Connector, your domain administrator must assign a phone number to you, so that you can receive incoming Circuit phone calls.

  • When using the ATC either with OpenScape Cloud or with your on premise
    PBX, your domain administrator must enable the telephony support for you, so that your office phone number will be used to make and receive phone calls in Circuit.


The first time that you attempt to sign in to Circuit (after the Telephony Connectors have been enabled) you will be asked to read and accept the Emergency Call Disclaimer.

By accepting it, you acknowledge that you will not use Circuit to make emergency calls as it might provide incorrect location information to the emergency service provider. If you need to make an emergency call, use a land line or a mobile phone.

If you use both the web and the mobile client, you will be asked to accept this disclaimer separately on each client. Once accepted, the Emergency Call Disclaimer will not appear again, except if the mobile client is uninstalled and installed again on the device(s).


The Phone calls conversation contains the logs of all the phone calls made through your work number via Circuit or desk phone. In addition, you can use this call log to directly place phone calls via Circuit to any of the contacts or numbers listed in the log.

  1. To open the call log, click or tap the Phone calls conversation in the conversation selector.

    The Phone calls conversation view opens, displaying the call log (history) containing the following items:

    • Incoming calls

    • Outgoing calls

    • Missed calls and calls that could not be completed (shown in red color)

    • Redirected calls (forwarded or hunted)

    The call log is sorted by date and time.

  2. To place Circuit phone calls directly from the call log, proceed as described in Making a phone call.
