Overlapped IP Address
The BorderNet 4000 SBC supports overlapping private networks with common IP addressing scheme.
These topologies are frequently seen in managed service provider networks. Typically, VLAN tagging is
used to clearly distinguish between different overlapping networks. The BorderNet 4000 SBC’s interface
definition and peer binding has been enhanced to include specifying the VLAN tag associated with each
overlapped network. The BorderNet 4000 SBC uses this unique combination of SIP interfaces, peers, and
the VLAN tags to route traffic between various overlapping networks.
IPPBX Registration Support
The BorderNet 4000 SBC can process SIP registration requests from both the consumer devices (e.g.
IADs, soft phones, desk phones, mobile extensions, etc.) as well as from the IPBPBXs. IPPBX registration
support is implemented as per the guidelines in the SIP Connect 1.1 recommendation and the RFC
6140—Registration for Multiple Phone Numbers in the Session Initiation Protocol (SIP) — standard.
Specifically, the BorderNet 4000 SBC supports bulk registration of extensions from the IPPBXs.
IPsec Support
Internet Protocol Security (IPsec) is a suite of IETF-defined protocols for securing communications over
the IP networks. IPsec protocols offer a range of security functions including data integrity, anti-replay
protection, and confidentiality via authenticating and encrypting packets in each IP session. The
BorderNet 4000 SBC supports IPsec Authentication Header (AH), which is used to authenticate and
validate IP packets, as well as IPsec Encapsulating Security Payload (ESP). In the ESP mode, IP packets are
encrypted. The BorderNet 4000 SBC supports manual keying and IKE v1. The BorderNet 4000 SBC IPsec
implementation leverages built-in hardware encryption network processors included with the Network
Interface Cards (NIC).
External DNS Support
In addition to local DNS capability, the BorderNet 4000 SBC supports the capability to query external
DNS severs for URI resolution. The supported DNS queries include DNS SRV, DNS NAPTR, and DNS A
6
Release 3.1.0
record lookups. The BorderNet 4000 SBC DNS implementation is IPv6-compatible and standards-based.
The supported standards include RFC 3263, RFC 2782, RFC 2915 and RFC 3596. External DNS is useful
for call routing, address resolution, and supporting remote peer redundancy.
Emergency Services
The BorderNet 4000 SBC has the ability to recognize emergency service calls based on Emergency
Profiles configured on the system and can differentiate emergency calls from other calls.
The Call’s Req-URI is checked for matching entries in the Emergency Profile configured for the
Peer/Interface Service Profile. When a match is found, the call is marked as “Emergency” in the system
and the resource priority header is added to the message. The Emergency flag is available for routing to
provide custom behavior for such calls, and different Security Profiles can limit Emergency calls from the
Peer/Interface.
Flexible Media Routing
The BorderNet 4000 SBC Release 3.1 introduces Flexible Media Routing, which enables the BorderNet
4000 SBC to intercept media on a per-call basis.
Enterprise Routing
The BorderNet 4000 SBC’s Enterprise Routing achieves the maximum manipulation of digits, especially
in the Called Party Identity (the user part of the Request-URI). This is accomplished via the BorderNet
4000 SBC SIP Profiler, which can be applied as part of the treatment parameter in the Advanced Policy.
Filter Option for Reports
The generic Report Filter in the WebUI has been enhanced to accept Time Range (Start and End) and
Interface/Peer Name as user input (in addition to the Date filter) as search criteria.
User Security Enhancement
The Diagnostics menu required Administrative privileges in earlier releases. The user access
enhancements now allow users to view Diagnostics information with read-only access.
List Users Currently Logged In With Ability to Close Sessions
The list of users currently logged into the BorderNet 4000 SBC can be viewed via the Logged-In Users
screen in the WebUI. This feature provides Administrators with the ability to terminate currently active
UI connections.
Resolved Issues
Defect SBC00004105
Issue
A 5-minute interval report could not be opened.
Root Cause
If the report was opened while the database was updating, the Report Controller generated an
Error: Unable to open report exception.
7
Dialogic® BorderNet 4000™ Session Border Controller Release Notes
Description of Fix
The code has been modified so that when the database is being updated, a more meaningful
error message (Error: Database is being updated. Please try the operation again later)
is generated.
Defect SBC00004610
Issue
An extension to the current session timer was requested.
Root Cause
The maximum session timer duration was limited to 7200 seconds (or 2 hours) in previous
releases. Customers requested that this value be increased to 48 hours.
Description of Fix
The maximum session timer interval is now increased to 48 hours.
Defect SBC00004732
Issue
A software exception occurred after a provisioning change.
Root Cause
A race condition between call handling and provisioning triggered the software exception.
Description of Fix
The race condition is avoided by providing additional locking to ensure the exception does not
re-occur.
Known Issues
Defect SBC00005042
Issue
GIT Remote was not setup on a HA system after rollback from 3.1.0 to 2.2.9.
Workaround
In a few instances during rollback operations, the Login Status updates ended with "Data merge
conflicts" between the Active and Standby platforms. If sync errors occur during a failover after
a rollback from 3.1 to 2.2.x/3.0, the Active platform can be "Reset" (if the other platform is in
Standby state) from System Information screen. This will force the failover operation, and
systems should automatically sync. An enhancement will be made in a future patch to
automatically correct such merge conflicts.
