New Features
DGW-15150 - Optimizations for new AMD Ryzen CPU
The following optimizations have been performed on the new AMD Ryzen CPU:
Improve scheduling between real-time threads and the Virtual Machines;
The SSD size value is now being cached to avoid potential lockups.
DGW-14415 - Improve P-Preferred-Identity (PPI) privacy in the Call Router
Incident Number: 15135
The Crout.SignalingProperties.Privacy parameter has been modified:
Added a new "AssertedId" setting to use P-Asserted-Identity and Privacy "id" when restricted;
Renamed the "Id" setting to "PreferredId".
Issues Fixed
DGW-15172 - Sentinel CS: The "Local Firewall" Web page was missing
The web page "Local Firewall" is now correctly present under the "Network" section on Mediatrix CS.
DGW-15077 - SBC: Support additional elliptic curve key exchanges for TLS
The Sbc service now supports the following elliptic curve key exchanges when using TLS:
x25519
secp256r1
x448
secp521r1
secp384r1
DGW-15035 - Documentation: Missing recommendation about SRTP and Session Refresh
In order to improve SRTP interoperability, it is preferable to use the UPDATE method instead of using re-INVITE for SIP Session Refresh, since an UPDATE usually contains no SDP.
The recommendation has been documented in the following parameters:
SipEp.DefaultSessionTimerEnable
SipEp.SessionRefreshRequestMethod
Known Issues
There are no known issues.
