Status
Description
KI-00024.0
(4.0.0000)
Resolved in 8.3.4675.0
Summary
After x weeks of operation recordings are terminated prematurely due to timeout on passive, SPAN-based direct NIC capturing solutions with specific HW/NIC/Virtual env conditions. In some conditions NIC/winpcap and OS clock is out of sync and over time (more weeks) the clock drift can accumulate and reach call timeout threshold.

Impact
- only impacts Passive SPAN-port based recording - does NOT affect Media Collector source and remote capturing on Media Collector (most Lync recording deployments) - the issue happens on rare combinations of specific platforms depending on NIC, NIC driver and virtualization environment (cases found in virtualized, but SPAN port based systems) - it might happen several weeks after recorder service has been up and running (depends on hw) - recording sessions terminated prematurely (before call ends) with end cause: call timeout (calls are only partially recorded)

Workaround
- Set higher call inactivity/timeout threshold (def 180 sec -> 600 sec) - Restart recorder service every weekend
KI-00007.0
(7.0.4314.0)
Resolved in 8.3.4668.0
Summary
Call length mismatch due to silence suppression If there is no RTP sent in any direction since both side are on mute/do not talk Lync stops sending RTP (or at call start does not start sending RTP). These gaps between voice parts (where RTP is sent) are filled, but the gap (if there is any) between call start - first voice RTP and last voice RTP - call end cannot filled.

Impact
- this issue leads to losing silent segments, but not actual voice recording - it leads to time difference between presented recording time and actual recording time of media - mostly conference calls are affected, especially the first participant who is on mute until others arrive

Workaround
- there are currently no known workarounds
KI-00057.0
(7.0.4314.0)
Resolved in 8.3.4669.0
Summary
After updating to Skype for Business clients, P2P calls are dropped when proxy server based recording is used.

Impact
- P2P calls dropped when the new Skype for Business client is used - effects all P2P calls - all installations are effected where proxy server based recording is used

Workaround
- Currently there are no known workarounds
KI-00037.0
(7.0.4314.0)
Resolved in 8.3.4693.0
Summary
Using a very large AD might cause timeout issues in the AD sync process. An AD timeout can lead to unwanted reconfiguration of the recorded users when only a subset of the configured users are retrieved from the AD during the sync process due to timeout.

Impact
- if the AD query runs too long, it can lead to unwanted reconfiguration of the recorded users, which can result to loss of recordings - there is no indication or alert if timeout occurs

Workaround
- include (ObjectCategory=person) in the search filter to reduce search time - increasing the timeout value on the AD side might prevent this issue
KI-00087.0
(7.0.4314.0)
Resolved in 8.4.4696.0
Summary
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.

Impact
- 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

Workaround
- configure SMTP server settings
KI-00147.0
(7.0.4314.0)
Resolved in 8.6.4809.0
Summary
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.

Impact
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.

Workaround
Disabling the session timer or media bypass completely resolves the issue
KI-00167.0
(7.0.4314.0)
Resolved in 8.7.4831.0
Summary
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

Impact
- 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

Workaround
- currently there are no known workarounds
KI-00187.0
(7.0.4314.0)
Resolved in 8.8.4874.0
Summary
Siren7 decoding problem is causing garbled decoding of voice in certain cases.

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

Impact
- 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

Workaround
- currently there are no known workarounds
KI-00307.0
(7.0.4314.0)
Resolved in 8.8.4966.0
Summary
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.

Impact
- 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

Workaround
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. https://quickview.cloudapps.cisco.com/quickview/bug/CSCvb32957
KI-00477.0
(7.0.4314.0)
Resolved in 8.9.5075.0
Summary
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.

Impact
- 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

Workaround
- The RTF message format can be disabled by a client policy, for more information see https://docs.microsoft.com/en-us/powershell/module/skype/set-csclientpolicy, DisableRTFIM
KI-00457.0
(7.0.4314.0)
Resolved in 9.0.2.5381
Summary
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.

Impact
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.

Workaround
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 https://demo.verba.com/verba/test/regex.jsp Enter the regexp value in the input box, then press the Test button to verify the expression.
KI-00587.0
(7.0.4314.0)
Resolved in 9.6.0.5944
Summary
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.

Impact
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. 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.
KI-00018.0
(8.0.4628.0)
Resolved in 8.3.4670.0
Summary
Short extra Lync recording segments in the beginning of Edge calls Routing of media streams might be changed up to 10 seconds into a call by Lync. In case multiple Verba recorders are used with proxy recording, the modified media stream might be process as a new call.

Impact
- effects Lync / Skype for Business recording, in proxy mode and only in redundant recorder setup - effects minor subset of calls going through Lync Edge servers - the beginning of the call might be cut off into a separate short recording

Workaround
- currently there are no known workarounds

8.3.4675.02015-03-16
RI-005480Recording - Lync/SfB
RTCP MUX with RTP was not handled properly in SDP compiling for Skype for Business calls

Impact
- P2P calls dropped when the new Skype for Business client is used - effects all P2P calls - all installations are effected where proxy server based recording is used
8.3.4669.02015-02-17
RI-005581Recording - Avaya
DMCC event processing can get blocked

Impact
- only Avaya AES-based recording is affected - recordings of <0.1 of calls might be lost due to race condition
8.3.4674.02015-03-09
RI-005446Platform - Media Processing
Short extra Lync recording segments in the beginning of Edge calls resolved using "recorder stickiness" - Recorders now advertise IDs of handled calls to media collectors / proxies, therefore the same media is always sent to same recorder even if it shows up on different collectors

Impact
- effects Lync / Skype for Business recording, in proxy mode and only in redundant recorder setup - effects minor subset of calls going through Lync Edge servers - the beginning of the call might be cut off into a separate short recording
8.3.4670.02015-03-02
RI-005461Platform - Media Processing
RTP processor threads can fill gaps in Discontinuous Transmission (Silence suppression) even in the beginning and end of a stream

Impact
- this issue leads to losing silent segments, but not actual voice recording - it leads to time difference between presented recording time and actual recording time of media - mostly conference calls are affected, especially the first participant who is on mute until others arrive
8.3.4670.02015-02-20
If you are using the effected components, we recommend a software update.
