1.1.2.4 Mediant 1000 MSBG
This release supports the following existing hardware platforms:
Mediant 1000 and Mediant 1000B chassis. The Mediant 1000B chassis is based on
the incumbent Mediant 1000 chassis, but designed to support Advanced Mezzanine
Card (AMC/AdvancedMC) form-factor modules. This chassis provides eight AMC slots
on its rear panel for housing single and mid-sized AMC modules. This chassis hosts
the CRMX module (instead of the CMX) for supporting both VoIP Gateway and MSBG
data-routing functionalities. The Mediant 1000B also provides support for the regular
Mediant 1000 telephony modules (i.e., FXS, FXO, and digital PSTN).
Note: The AMC chassis slots must only be housed with AMC modules approved
and homologated by AudioCodes – ensure not to use these slots for AMC
modules and configurations that have not been approved.
CRMX module, providing three LAN 10/100/1000Base-T ports and one WAN port in
one of the following configurations (customer ordered):
•CRMX-C module: RJ-45 port (4-twisted pair copper cabling) providing 1 Gigabit
Ethernet (GbE) interface for connection to the Internet
•CRMX-S module: 1000Base-SX optical fiber port (multi-mode fiber)
•CRMS-L module: 1000Base-LX optical fiber port (single-mode fiber)
•CRMX-T: RJ-48c (2-twisted pairs copper cabling) Data Service Unit/Channel
Service Unit (DSU/CSU) T1 WAN port, for connecting to a T1 line
•CRMX-SD module: Symmetric High-Speed Digital Subscriber Line (SHDSL). This
module provides 3 LAN ports and 1 SHDSL port. The SHDSL port has 4 wire-
pairs, and therefore, supports 4 SHDSL ports on a single physical connector.
SHDSL port specifications:
♦Conforms to ITU G.991.2 Annexes A, B, E, F and G SHDSL
♦Up to 5,696 Kbps over a single wire pair
♦Up to 22,784 Kbps over four wire pairs bonding, according to SHDSL.bis

1.2 SIP New Features
This section lists the new SIP features in Release 6.2.
1.2.1 SIP General New Features
The device supports the following new SIP general (Gateway and SBC applications)
features:
1. Maximum SIP Message Size:
Product
MP-11x MP-124
Mediant 600 Mediant 1000
Mediant 800 MSBG Mediant 1000 MSBG
Mediant 2000
Mediant 3000/TP-6310 Mediant 3000 HA/TP-6310
Mediant 3000/TP-8410 Mediant 3000 HA/TP-8410
Management Protocol
Web INI SNMP EMS CLI
This feature supports the configuration of the maximum size for each SIP message.
This allows the user to limit the size of the SIP message that is sent over the network.
The device rejects messages exceeding this user-defined size. The maximum SIP
message size is defined using the new parameter, MaxSIPMessageLength. The
maximum size can range between 1 and 50 Kbytes.
2. Time Limit for Receipt of SIP Messages:
Product
MP-11x MP-124
Mediant 600 Mediant 1000
Mediant 800 MSBG Mediant 1000 MSBG
Mediant 2000
Mediant 3000/TP-6310 Mediant 3000 HA/TP-6310
Mediant 3000/TP-8410 Mediant 3000 HA/TP-8410
Management Protocol
Web INI SNMP EMS CLI
This feature provides a 30-second period (limit) for the receipt of a complete SIP
message on the device’s TCP socket. For example, if the device receives a SIP
message whose SIP Content-Length header is larger than the actual message body,
the TCP socket remains open and waits for the rest of the message body to arrive.
During this time, no other messages are accepted by the socket. However, if the
remaining message body does not arrive within 30 seconds, the device terminates the
session on the socket in order to allow new messages to arrive.

Version 6.2 19 December 2010
SIP Release Notes 1. What's New in Release 6.2
3. SDP Offer/Answer Negotiation upon Modified Session:
Product
MP-11x MP-124
Mediant 600 Mediant 1000
Mediant 800 MSBG Mediant 1000 MSBG
Mediant 2000
Mediant 3000/TP-6310 Mediant 3000 HA/TP-6310
Mediant 3000/TP-8410 Mediant 3000 HA/TP-8410
Management Protocol
Web INI SNMP EMS CLI
This feature enables the flexibility of ignoring a new SDP re-offer (from the media
negotiation perspective) in certain scenarios (such as session expires). According to
RFC 3264, once an SDP session is established, a new SDP offer is considered a new
offer only when the SDP origin value is incremented. In scenarios such as session
expires, SDP negotiation is irrelevant and thus, the origin field is not changed.
Even though some SIP devices don’t follow this behavior and don’t increment the
origin value even in scenarios where they want to re-negotiate, the device up till now
re-negotiated regardless of the origin field value. Since this caused problems in certain
scenarios, this feature resolves this by assuming that the remote party operates
according to RFC 3264, and in cases where the origin field is not incremented, the
device does not re-negotiate SDP capabilities.
This feature offers the following options:
•The device negotiates any new SDP re-offer, regardless of the origin field
(default).
•The device negotiates only an SDP re-offer with an incremented origin field.
This feature is configured using the new parameter, EnableSDPVersionNegotiation.

Management Protocol
Web INI SNMP EMS CLI
This feature provides support for securing the device’s resources against SIP spam
and invalid SIP messages:
•Securing memory resources:
♦Socket Resource Abuse: Connections that are established without
subsequent data transmission are released (after one minute), allowing the
establishment of new connections.
♦Established Connection Flood: The device detects and subsequently
discards any flood of “false” connections (which typically prevents
establishment of new legitimate connections). The device effectively
manages its socket resources, releasing unused sockets for required
connections.
•CPU:
♦Loop-Amplification Scenario: The device prevents routing between its
interfaces. The attacker needs to convince the device to re-write a request to
a location, which resolves to the device itself. This can be done if the routing
is according to the SIP Request-URI header and the address specified is the
device’s IP address. This results in the server over loading itself. Another
method for creating loops is through a SIP proxy to which the device routes
and this proxy routes it back to the device.
For MSBG products, the SBCMaxForwardsLimit parameter is used to limit
the SIP Max-Forwards header value.
♦Malformed SIP Requests: Malformed SIP message requests are typically
sent to cause false, expensive SIP parsing, thereby wasting CPU resources.
The device’s parsing has been significantly improved to detect malformed
messages and to reject such messages in early parsing stages.
•SIP Vulnerabilities:
♦General Parser Errors: Parser errors (invalid SIP messages) do not cause
loss of service.
♦SIP Content-Length header greater than the message’s body: This can
cause delayed or no service by causing a TCP to wait for that body to arrive.
- TCP: maximum message length is dictated.
- UDP: Content-Length is validated with the packet size. If the packet size is
not as declared in the Content-Length header, only the actual body size is
validated and the Content-Length header is ignored.
♦Invalid Content-Length header: The device ignores such messages.
♦Null characters are allowed only in the SIP message’s body according to the
SIP ABNF. The device rejects messages that arrive with null characters in
the headers part of the message. This ensures that the device doesn’t
forward invalid messages that can be harmful to the internal network.
