MBG
11.2 runs on Mitel Standard Linux Release 11.0. Before upgrading
to MBG 11.2, verify that your server hardware is compatible with
CentOS Linux 7.
MSL 11.0 and later releases use the Mitel Software Download
Center, supported by a global content distribution network to increase
speed and reliability of downloads.
For Virtual MBG deployments, the Small Business configuration
now requires 2 GB of RAM. Refer to the Virtual Appliance Deployment
Guide.
Management
The MiVoice Border Gateway
(MBG) user interface (UI) is restructured to provide a more service-oriented
solution. "Remote Proxy configuration” is now available in the MBG
UI.
The MBG UI is enhanced to include an option that enables searching
within the UI. This option is available on the main menu bar at
the top right corner of the interface. The administrator can use this
feature to find where to configure or view commonly used MBG options.
The MBG Dashboard has a new look and feel. The purpose is to
provide more visual or per-service indicators to the administrator.
The Packet Trace diagnostics tool is redesigned to indicate
that there are two types of traces and that the data captured by
each is different.
The global trace is now a rotating capture
(that is, the global tcpdump rotates the trace file automatically
every time the file size reaches 200 MB) limited to 1.2 GB and does
not stop when leaving the interface. This trace automatically stops
when there is less than 5 GB of disk space left.
Starting the global trace also starts signalling pcap, mainly
to help troubleshoot MiCollab client that connect over SIP TLS.
The Fetch all button downloads all the traces and the same logs
that would be included in Fetch Logs.
MiNet Devices
Mitel 6905, 6910, and
6970 series IP Phones can be used as teleworker devices on MBG with
a MiVoice Business.
SIP Devices
Support for push notification
on MiCollab Android client in MiCollab 9.0.
MBG 11.2 improves the existing SIP LOCAL streaming mode.
Note: Refer
to the MBG Engineering Guidelines (available at Mitel Document Center)
for specific requirements of SIP LOCAL streaming.
SIP Trunks
As of MBG 11.0, SIP Trunking
is supported over TLS in SRV MODE.
SIP Trunking resiliency with DNS SRV has been enhanced to support
re-registration before sending a call to a new gateway. This feature
is supported for providers who use the same credentials for all
SIP requests.
Call Recording
MBG is now enhanced
to provide SIPREC service in addition to SRC. SIPREC service is
an industry-standard protocol to record SIP devices by enabling
external Call Recording Equipment (CRE) to record audio calls.
Default SSL ciphers
For the new installations,
the default SSL ciphers will be Intermediate (TLS v1.2+).
Note:
When
a legacy device is upgraded to Release 11.2, there will be no change
in the SSL cipher configuration.
For enhanced security, it is recommended that you set the SSL
ciphers for the existing systems to Intermediate. For doing
this, the admin will need to change the SSL ciphers from Legacy to Intermediate.
Compat 8.1 is no longer available.
To change the SSL ciphers configuration, go to System > Settings > Service
Parameters, and in the SSL ciphers field, choose an option
(Legacy/ Intermediate/ High) from the drop-down list.
Auto-Load of new Web Certificate
webRTC
supports automatic detection of changes in the web certificate and
uploads the new certificate. Therefore, it is no longer required
to restart webRTC for the new certificate to take effect.
