Known Critical Issues

First Affected
Resolved in 8.4.4696.0
Amazon permanently disabled the built-in Amazon SES SMTP account and it can no longer be used to send email alerts from the system. Customers need to configure their own SMTP server for sending emails. This is due to an Amazon policy decision outside of our control.

- all deployments are affected where the built-in Amazon SES based account was configured to send email alerts - the system cannot send any alert until it is reconfigured to use another SMTP server

- configure SMTP server settings
Resolved in 8.6.4809.0
There is one way audio in recordings after SIP re-invites when media bypass is active. The SfB/Lync Filter service does not recognize the SIP re-invite messages properly when media bypass is active, and the call is only partially rerouted through the proxy. This results in one way audio in the recordings after the first re-invite. The re-invite period is controlled by the session timer configured for the connection between the gateway and the SfB/Lync system.

Am I affected?
All 7.0 and later SfB/Lync recording deployments using proxy based recording are affected where media bypass is configured with SIP session timer.

The Verba SfB/Lync Filter does not recognize SIP re-invite messages properly when media bypass is active and the call is only partially rerouted through the proxy. This results in one way audio in the recordings after the first re-invite. The re-invite period is controlled by the session timer configured for the connection between the gateway and the SfB/Lync system. When the default SIP session timer setting (1800s) is used, the first re-invite is sent after 15 minutes. Thus all inbound or outbound calls longer than 15 minutes are affected. Prior to the re-invite, recordings contain both directions.

Disabling the session timer or media bypass completely resolves the issue
Resolved in 8.7.4831.0
Recording failure due to new, unsupported RTP header extension in latest Skype for Business 2016 clients.

Am I affected?
Affects all Skype for Business 2016 P2P calls between UCCAPI/16.0.6741.5270 OC/16.0.6741.2021 or newer clients

- media stream processing error causes recording failure due to a new RTP header extension - more information is expected on other affected call scenarios and client/server versions - affects all Verba releases with all types of SfB/Lync recording deployments

- currently there are no known workarounds
Resolved in 8.8.4874.0
Siren7 decoding problem is causing garbled decoding of voice in certain cases.

Am I affected?
All Lync/SfB recording deployments are affected.

- Intermittently causes garbled voice recording when Siren7 voice codec is used for the call - The recording quality is varying for the garbled recordings, from light impact to severe degradation of quality - Siren7 voice codec is mainly used for Lync 2010 Windows endpoints and Skype for Business 2015 IOS/Android devices when network is degraded - Siren7 voice codec is also used for Lync 2010/2013 and Skype for Business 2015 meetings during poor network conditions

- currently there are no known workarounds
Resolved in 8.8.4966.0
In a HA deployment, when multiple Verba Recording Servers are configured, then if the network connection goes down on any of the Verba Recording Servers, all IM communication stops as some of the Cisco IM&P Servers will not be able to establish the connection to another Verba Recording Server, causing all IM to stop. Cisco IM&P Servers are not able to reconnect to the Verba Recording Server after the connection is broken.

Am I affected?
All Verba deployments configured for Cisco IM recording or ethical wall are affected where multiple Verba Recording Servers are deployed in a failover configuration. All Cisco IM&P versions are affected.

- Recording/Compliance server failover does not work, the Cisco IM&P Server is not able to properly detect Verba Recording Server network failures - All IM communication is blocked by the Cisco IM&P Servers (compliance mode) if Fire&Forget is disabled

Cisco has fixed the issue and released an updated library. Now the library correctly handles OS level TCP keep alive. In addition to replacing the library, two registry entries are required under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters: KeepAliveTime=10 and KeepAliveInterval=5000. A server restart is required for the new settings to take effect.
Resolved in 8.9.5075.0
Lync / Skype for Business IM conversations might not be recorded after recording and processing 10,000 RTF based messages.

Am I affected?
All Lync / Skype for Business IM recording deployments are affected. This issue affects IM conversations which are using the RTF format. Lync 2013 or newer desktop clients are using the RTF format for P2P IM conversation when both participants are using a desktop client. Conferences, mobile, and consumer Skype conversations are not affected by this issue.

- When the instant message is transmitted using the RTF format, the Verba Lync / SfB IM Filter application (on the FE servers) can use all available Window handles due to the improper deallocation of the RTF parser. - The service stops processing RTF based instant messages after approx. 10,000 RTF messages (after all Windows handles are consumed) - No alert or notification sent when the issue occurs

- The RTF message format can be disabled by a client policy, for more information see, DisableRTFIM

In case an invalid regular expression is used for internal number patterns, calls are not recorded.

Am I affected?
All version 7.x or later recording deployments where the Verba Passive Recorder Service, the Verba Media Collector and Proxy Service and the Verba Unified Call Recorder Service are used for recording could be affected.

Calls are not recorded by the related service when an invalid regular expression is applied for one of the following settings: - Passive Recorder \ Basics \ Internal Number Pattern - Media Collector and Proxy \ General \ Internal Domain, Numbers Pattern - Unified Call Recorder \ Recording Providers \ General \ Internal Domain, Numbers Pattern The system uses these configuration settings to identify the direction of recorded calls. The affected services do not raise an alarm, except the Verba Unified Call Recorder Service which will send a CallProcessing alert.

Remove any invalid regular expressions from the following configuration settings: - Passive Recorder \ Basics \ Internal Number Pattern - Media Collector and Proxy \ General \ Internal Domain, Numbers Pattern - Unified Call Recorder \ Recording Providers \ General \ Internal Domain, Numbers Pattern An online regexp validator is available to verify regexp patterns at Enter the regexp value in the input box, then press the Test button to verify the expression.

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

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.

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.

Currently there is no workaround other than disabling Teams or Azure VM calling entirely for the recorded users. 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 2020 with the enhanced version of the Proxy Server.
Resolved in 8.4.4693.0
Reconnect issue between the Verba Lync Filter and the Verba Media Collector & Proxy components In case a large number of Filters are trying to reconnect to the Media Collector & Proxy service at the same time, none of them will be able to connect due to an issue in the connection handling process. This could be the case when there are at least 8-10 or more Filter applications in the system and the Media Collector & Proxy service is restarted. This issue only occurs if there are a relatively large number of Filters (8-10 or more) trying to reconnect at the same time.

- If the Filter component is not able to connect to the Media Collector & Proxy service, signaling information cannot be shared, leading to a call recording service outage - If system monitoring is enabled and configured properly, the system sends alerts for all Filter connection errors when the Media Collector & Proxy service goes down - All Verba v8.3 deployments for Microsoft Lync 2010/2013 and Skype for Business whith Proxy, Edge, Mediation and AVMCU based recording are affected

- First all Filter services need to be stopped, and then started in a sequential fashion
Resolved in 8.5.4804.0
Network port mirroring based SIP and SCCP recording might suffer from memory leak due to a TCP session cleanup bug found in TCP/IP reassembling

Am I affected?
All 8.4 and 8.5 port mirroring based recording deployments are affected. However Lync/SfB recording deployments are not affected, unless Mediation server based recording is used and standard SIP traffic is captured with the same component.

If the process runs out of memory and memory allocation fails for recorded sessions, then loss of recording might occur until the service restarts. The amount/speed of the memory leak highly depends on the amount of monitored traffic and the number of total TCP sessions monitored.

There is no known workaround.
Resolved in 8.5.4804.0
Data retention policies (except upload and export) using the global schedule (not custom) are not executed.

Am I affected?
All 8.4 and 8.5 versions are affected.

This issue can not lead to data loss, however storage policies with non-custom schedules will not be executed. The following storage policies will only be executed when custom schedules are used: Archive in DB and Move Media, Archive in DB, Move Media, Delete, Export, Transcode, Create Phonetic Index, Delete Phonetic Index. The system does not send alerts or notification messages, there is no indication of the problem other than the policies are not running.

Configuring a custom schedule for your data retention policy will enable the policy.

In case a large number of Filters are trying to reconnect to the Media Collector & Proxy service at the same time, none of them will be able to connect due to an issue in the connection handling process. This could be the case when there are at least 8-10 or more Filter applications in the system and the Media Collector & Proxy service is restarted. This issue only occurs if there are a relatively large number of Filters (8-10 or more) trying to reconnect at the same time.

- If the Filter component is not able to connect to the Media Collector & Proxy service, signaling information cannot be shared, leading to a call recording service outage - If system monitoring is enabled and configured properly, the system sends alerts for all Filter connection errors when the Media Collector & Proxy service goes down - All Verba v8.3 deployments for Microsoft Lync 2010/2013 and Skype for Business whith Proxy, Edge, Mediation and AVMCU based recording are affected
If you are using the effected components, we recommend a software update.
