Enable call control with Yealink headsets – Yealink SDK not included in ProCall 7 Enterprise as of R 7.4.1 due to false positive Sophos warning message


After a false positive virus warning message "Malicious exploit" appears for the Yealink SDK from Sophos, the Yealink SDK (libyealinkusbsdk.dll) for call control was no longer delivered with the installation in ProCall 7 Enterprise from release 7.4.1 ( 26.04.2022 ).
Please note that even when updating from 7.4.0 to 7.4.1, the SDK is no longer installed with it.

If you urgently need the functionality "Call control with Yealink headsets", you can request the SDK (libyealinkusbsdk.dll) from Yealink and copy it manually to the new subfolder "\driver\x86\Yealink" to be created in the ProCall client installation.

If you are already using ProCall Enterprise version 7.4.0, you can also use this method to temporarily copy away the DLL file before updating to 7.4.1 and then copy it back again after the update.

Yealink is working hard to resolve the false positive virus alerts when using "sophos Central Intercept X Advanced with XDR".
As soon as a solution is available, the Yealink SDK will again become an official part of ProCall 7 Enterprise.

In Tech Essentials April 2022, we already pointed out the warning message. We have updated the corresponding article according to the latest findings:

Call Routing via group call/overflow group: New hints for connecting ProCall Enterprise and STARFACE PBX

Particularly in the case of calls via group numbers or overflow groups, only the caller's phone number is transmitted to the forwarding destination or the drop destination, the call window does not show any information about the call routing via group number or overflow group number at the forwarding destination, i.e. the call window does not show any information Forwarded by...


ProCall mobile app for Android: When dialing via softphone line, a GSM call is initiated – cause and procedure


If ProCall mobile is activated as an Android call account and a Sophos MDM (Mobile Device Management) is in use, it can happen that a GSM call is initiated when dialing via softphone line. Here, Sophos seems to intervene when another app is activated as call account and allows dialing via GSM only. As a workaround, the Android call account can be deactivated and the ProCall mobile in-app call window can be used instead.
