Hotfix number	Affected components	Description
7.0.20.1	OII	Collection of OII fixes made for previous releases
7.0.20.2	ECF Web Server	Collection of UI corrections
7.0.20.3	-	Hotfix doesn't exist
7.0.20.4	CEM	Correction to address Python vulnerabilities in CEM package Highly recommended for all customers
7.0.20.5	-	Hotfix doesn't exist
7.0.20.6	-	Hotfix doesn't exist
7.0.20.7	Call Dispatcher (CD), Media Routing Server (MRS), and SIP Bridge	Audio of third party in a conference was not properly included in the recording. SIP glare was not handled correctly, causing problems, such as agents not being able to hang up calls. In a complex call scenario where Quality Monitoring Server (QMS) and Multiterminal Desktop (MTD) / Simultaneous Ring Mode (SRM) are in use, hub processing failed in Media Routing Server (MRS) and caused missing RTP streams. If the Sinch Contact Pro system used either stereo recording or Quality Monitoring Server (QMS) with separate audio streams configured, and an agent transferred the customer call to another agent, the audio channels of the recording and QMS got switched. This meant that customer’s audio appeared in the agent’s channel and the other way around.
7.0.20.8	RI	Incorrect value for waiting duration
7.0.20.9	ECF Web Server	Connection to Agent Server silently lost
7.0.20.10	Integration Interfaces	If Presence Synchronization Interface (PSI) was enabled in Infrastructure Administrator (IA) but Teams integration was not configured in System Configurator, PSI went to Near failure state for HAC. IA shows this as a yellow exclamation mark.
7.0.20.11	Reporting Database Server	A subtype for internal action item was missing from reporting, which caused issues with customers' reports.
7.0.20.12	ECF Web Server	Dashboard failed to send SMS to all recipients.
7.0.20.13	OII	When Contact Pro is integrated with SAP CRM via the SAPphone interface and a call is answered in CP and disconnected, CP goes to wrap-up but OII ends it immediately. Now OII doesn’t end wrap-up if user is not subscribed to the ICI interface.
7.0.20.14	ECF Web Server	Several fixes to Communication Panel
7.0.20.15	ECF Web Server	Several fixes made related to the window sync mechanism used between embedded CP and pop-out CP
7.0.20.16	Call Dispatcher (CD) and Media Routing Server (MRS)	When a consulted party left a conference call, but the caller and consulting agent continued talking, audio issues occurred in environments without MRS for recording, QMS, NAT this resulted in caller stream going directly to agent instead of the conference HUB, which caused one-way voice issues where caller could not hear agent.
7.0.20.17	ECF Web Server	Dial tone didn't end after calling a logged-out agent.
7.0.20.18	Call Dispatcher (CD)	Call Dispatcher crashed causing all calls in the system to get disconnected in some complex call scenarios where there were two related calls (for example consultation and transfer) and one of them wasn't timely disconnected.
7.0.20.20	ECF Web Server	After restarting the PC, the first outgoing or incoming call had no audio. CP blocked emails if the “To” address contained Scandinavian letters.
7.0.20.21	ECF Web Server	Calls made with a Sennheiser device experienced call control issues.
7.0.20.22	OII	Ready button on the SAP CIC0 telephony interface does not end the wrap-up time when using Communication Panel. This hotfix will add an optional registry setting SAPphoneEndWrapUps which can be used to disable the feature by giving value 0.
7.0.20.23	ECF Web Server	This hotfix also resolves the microphone issue, so we recommend that you install it. When a user made an outgoing call, two separate calls were created to the same number, each with its own call ID, and both were marked as abandoned. Now, calling the same number within a short interval (less than 1000 ms) is prevented. A recent browser update may cause Communication Panel to use the computer’s default microphone instead of the one the user has selected. This can be confusing on systems with several audio devices, where the intended device isn't the one actually used. Occasionally, the PDF feature failed to show or print the conversation's text. Updating the style sheet and setting Arial as the new default font fixed the issue.
7.0.20.24	Call Dispatcher (CD)	Resolved an issue where an unterminated conference call would create a duplicate audio stream when transferred. This change corrects the call termination process, eliminating the audio quality degradation and glitches that previously occurred during call transfers.
7.0.20.25	RESTful Interfaces, OII, Email Sender, and ECF Web Server	Several security vulnerabilities addressed
7.0.20.27	Call Dispatcher (CD)	B-number modifications done with edit masks did not affect R-number when a caller transferred the call and the R-number was the original unmodified B-number and not the modified B-number as it should.
