Certain calls between Skype for Business and Teams or Azure VoiceMail cannot be recorded - KI-0058

Summary

Certain calls between Skype for Business and Teams or Azure VoiceMail cannot be recorded in Verint Financial Compliance Capture (formerly Verba)

Am I affected?

All Sykpe for Business recording installations are affected where the recorded users can call Teams users or place voicemail messages in Azure VoiceMail.

Impact

We would like to notify our customers and partners that certain Skype for Business calls cannot be recorded when a recorded Skype for Business user is calling a Teams user and one of the participants is outside of the corporate network, or a recorded Skype for Business user is placing an Azure VoiceMail message.

This limitation is caused by the new call setup procedure, and specifically in ICE negotiation, introduced in Teams and Azure VoiceMail, which prevents the recording system to redirect and force the calls to the Skype for Business Edge Server where the Media collector can fork the related media streams. Since the system is not able to capture the media streams related to these calls, these calls are not recorded. No alerts are raised unless CDR reconciliation is enabled.

Workaround

Currently, there is no workaround other than disabling Teams or Azure VM calling entirely for the recorded users.

Resolution

We are actively working on implementing a new solution which extends the capabilities of the Proxy Server to be able to relay these type of calls too. It requires a major change in the architecture by allowing the Proxy Server to relay calls with external participants through a public interface.

It also means that that calls which are currently routed through the Skype for Business Edge Server and forked by the Media Collector Service will be routed through the Proxy Servers that same way as calls with internal or PSTN participants. We are currently targeting July with the enhanced version of the Proxy Server.
