Version 2.6.0
2.1
What's New in Version 2.6.0
The following new features are supported in Version 2.6.0:
The MP-202 now supports SIP over TLS. TLS is a security mechanism that operates on top of TCP
enabling SIP entities to send and receive data in a secure and authenticated manner.
The MP-202 now supports STUN, a light-weight protocol that enables clients behind NATs
(Network Address Translators) to discover the presence and types of NATs and firewalls between
them and the public Internet. It also enables the client to determine the public IP addresses
allocated to the NAT. (For more information, see RFC 3489 STUN - Simple Traversal of UDP
through NATs.)
Mass Provisioning:
•
The MP-202 enables downloading of an alternative format of the configuration file in ".ini-file"
format from a remote URL. When the MP-202 has a configuration file URL with the .ini
extension, it will expect it to have a flat .ini file-like format, for example:
rg_conf/voip/signalling/sip/proxy_address=10.16.2.4
rg_conf/voip/signalling/sip/proxy_timeout=3600
•
The MP_202 enables displaying and saving of the current configuration in ini-file format: A new
checkbox was added to the configuration file Web page – "Display configuration in flat .ini-file
format". When it is checked, the configuration file is displayed in flat .ini-file format. If the user
then selects to save the configuration file, it will be saved as a .ini file. The option '-i' in
rg_conf_print enables this at the CLI level.
•
The MP-202 enables displaying and saving of only the modified configuration parameters: A
new checkbox was added to the configuration file Web page - "Display modified configuration
fields only". When it is checked, only the configuration parameters that have values other than
the default values are displayed and saved. The option '-m' in rg_conf_print enables this at
the CLI level.
•
A new option was added to enable periodic checking for a new configuration file at the user-
configured URL.
A new method for establishing 3 way conference calls via a remote Conference server was added,
based on RFC 4240.
Improved Syslog debugging messages for diagnostic purposes. The debugging traces' filter level
can be opened, closed or modified during run time.
SIP Security – the MP-202's firewall can be configured to block incoming packets that have the SIP
signaling port as their destination. The user can configure up to two SIP entities (for example, the
SIP proxy or an SBC) which are not to be blocked by the firewall.
Addition of a Keep Alive option using SIP OPTIONS Messages. A SIP OPTIONS message is sent
periodically to the SIP registrar entity. The periodic interval can be configured from the
VoIP>Signaling Protocol Web-page.
Addition of a distinctive Call Waiting tone. When an INVITE message is received during a call, the
MP-202 applies a special call waiting tone based on the content of Alert-info header if it exists,
instead of the default tone. The alert data in an INVITE message defines the called party ringing
tone/call waiting tone.
A new configuration parameter – "Connect on 180" has been defined. When this parameter is
enabled, media is connected upon receipt of 180, 183 or 200 messages. When the parameter is
NOT enabled, media is connected upon receipt of 183 and 200 messages only.
MWI notification is NOT generated if there is an ongoing call. The indication is generated when the
call ends.
Added FaxMaxRate negotiation. Negotiation takes place for T.38 SDP media attribute
"T38MaxBitRate". If the remote side requests a decrease in the value of this field, the DSP is
