RTCSP-1888
A revised SDK from the manufacturer has been implemented for the Windows client for call control with Jabra headsets. The SDK offers new possibilities and bug fixes. The previously used "Jabra Native HID API" (JabraNativeHid.dll version 1.4.308.0) has been updated to the current "Jabra SDK" (libjabra.dll version 1.8.8.5). All call control features implemented for ProCall have been retested. This includes mute/activate microphone, accept call, reject call, hang up connected call, hold call, retrieve call, accept second call (call waiting), reject second call, toggle calls, hang up connected second call. Furthermore, the list of tested Jabra headsets was extended. The tests were successfully completed with the Jabra headset types Engage 75 (via USB docking station) and Evolve2 65 (via BT dongle Link 380).

PAIM-1883
Fixed a bug where multiple call forwarding profiles with the same name on ProCall Client for Windows would display a smear character in the error message for them.

RTCSP-1814
In the server, the behavior of incoming calls via softphone was improved when a user has registered several cell phones ("for-king"). When one of the phones answered the call, too many (DropCall) push messages were generated to hang up the other devices. Also, another unnecessary (DropCall) push message was removed if the app was terminated without logging off before the call (e.g. by "killing" or crashing).

RTCSP-1801
If the PBX does not provide an SDP in the 200 OK during the SIP connection, an SDP is now observed in the 183 Session Progress.

RTCSP-1797
Fixed a bug on ProCall Client for Windows that increased the number of MMDevices audio key handles. This could cause the available handles to run out on systems such as a terminal server.

RTCSP-1788
In rare cases, a locally generated ringback tone was not terminated for outgoing calls. As of version 7.1.1, the ringback tone can come from the exchange ("Early Media"). If the exchange does not provide the tone, it is generated locally. In case of an error, the locally generated tone was started once too much due to a timeout error. In version 6.4.15 this function did not exist yet, but the timeout error mentioned above could occur elsewhere. Therefore, the cause of the error was also cleaned up in version 6.4.16.

RTCSP-1767
For softphone the internal processing time for incoming calls has been improved (time between "Invite" and "Trying"). The time can play a role if many softphone subscribers receive a call at the same time.

RTCSP-1592
Fixed a bug where the iOS ProCall Mobile app displayed multiple push notifications in case of missed calls.

The 64-bit Access Database Engine installation file can be found in the subdirectory "Supportfiles" of the UCServer installation directory (normally C:\Program Files\estos\UCServer).

Update 6.4.11.3356

Modified and new functions

PAIM-1615
The SMS provider Ecall has a new URL. There is a new URL for SMS pro-vider Ecall.ch. The new URL is: https://url.ecall.ch/api/sms?

Bug fixes and improvements

In the PBX Call Assist for Windows client, it was possible to execute commands (e.g. JavaScript, ActiveX) in the underlying Microsoft Internet Explorer remotely, i.e. from another PBX Call Assist client, via the contact portal or the multimedia business card or federation, using chat messages. A potential attacker could thus transfer any (malicious) software to the system and execute it there.

Recommendation:
estos recommends updating to the latest version of PBX Call Assist 3 (6.4.11. or higher).

PAIM-1723
It was possible to execute code via the chat window (see introductory text above about the release and recommendation. The problem was fi-xed.

PAIM-1715
A crash of the UCServer in connection with the archiving
Access database was fixed.

PAIM-1713
Error messages in the UMReplikator log have been improved.

PAIM-1706
After deactivating individual Windows notification sounds of the clients
in the system, these were no longer overwritten with the default value when the client was started.

RTCSP-1685
A problem with registration of softphone lines with www-Authentication header was fixed.

PAIM-1660
Since an update from MBCTI 5.1 to 6.4 no Windows domain authentica-tion is possible. The problem has been fixed, currently without TLS.

PAIM-1659
An attempt to connect to Active Directory via LDAP or LDAPS resulted in a UC server crash. This error has been fixed.

PAIM-1651
Chat messages are not displayed if the sender is blocked at the receiver (at user level).

PAIM-1646
The length of the message preview for push notifications has been in-creased from 100 to 2048 characters.

PAIM-1642
If "Working elsewhere" is selected in an Outlook appointment (instead of "Busy" or "Out of office"), this appointment is still displayed as "Busy" and my presence is displayed accordingly. But the behaviour should be like a free appointment and the presence should not change. This prob-lem has been fixed.

PAIM-1618
It could happen under certain circumstances (if an existing TAPI buffer for the TAPI interface was reduced in size) that service eucsrv.exe crashes. The problem was fixed, it is no longer possible to reduce an ex-isting buffer.

PAIM-1612
Admin: Offer menu items "Basic services" and "Synchronize contact data" if the "Events" page is selected. Previously it could happen that the menu item Events did not include the menu Basic Services. The menu has been adjusted.

PAIM-1485
It could happen that administrative keys were not displayed. This error has been fixed.

PAIM-1377
Server: Errormessage: 22018 [Microsoft][ODBC Microsoft Access Driver] Expression to complex. This error message occurred if there were more than 100 entries in the Connection-ID list. This error has been fixed.
