The following features were added to the IMG 10.3.1 release:
Engineering Release 4
The following features were added to the 10.3.1 ER 4:
Multi Router Traffic Grapher (MRTG) Tool
The Multi Router Traffic Grapher (MRTG) Tool is used to monitor various areas on network links. MRTG generates HTML pages containing PNG images which provide a live visual representation of this traffic.
See IMG 1010 - Overview of MRTG
Comedia for H.323
The IMG now supports Comedia for H.323. H323 uses the Comedia information internally; no Comedia information is shared with other gateways or endpoints.
See IMG 1010 - Symmetric NAT Traversal
Controlled Introduction Release
The following features were in the base 10.3.1 CI Release:
Folder changes for Cantata Re-branding
Some file and folder names have changed due to the change from Excel Switching Corp. to Cantata Technologies, as follows:
Various files such as licences, routing, and logs are now installed in the following folder: opt/cantata/common
Existing 10.3.0 configuration files will remain backed up in the following folder: opt/Excel Switching Corp/backup
Currently used configuration files are stored in opt/cantata/IMG/config
Backup 10.3.1 configuration files are stored in the following folder: opt/cantata/IMG/backup
ClientView Enhancements
Hosts and Usernames Retained in Login Pane History
See IMG 1010 - ClientView Properties.
ClientView Upgrades
When you upgrade to a newer version of ClientView, there may be some changes to panes or fields that affect your existing configuration. When you open an existing configuration file with a new version of ClientView, a log is generated that indicates any changes that would be required to the file. You are given the option to accept the changes or to not use the file.
Gateway Enhancements
Gateway Mask
Added a Gateway Mask field to the External Gateway pane to allow you to configure the IMG to accept calls from multiple gateways with one entry.
Added CLIP/CLIR for IDs
VoIP
New Mindspeed module enables support for new codecs and IP-IP transcoding density improvements (up to 1024 VoIP channels)
Wireless Codecs for SIP
The following wireless codecs are now supported for SIP:
AMR (license required)
Adaptive Multi-Rate (AMR) is a variable bit rate (VBR) codec - used in wireless GSM networks.
EVRC (license required)
Enhanced Variable Rate CODEC - used in wireless CDMA networks.
iLBC
iLBC (internet Low Bitrate Codec) is a free speech codec suitable for robust voice communication over IP for such applications as SIP Endpoints (soft phones) and Packet Cable. The codec is designed for narrow band speech and results in a payload bit rate of 13.33 kbit/s with an encoding frame length of 30 ms and 15.20 kbps with an encoding length of 20 ms. Typically used

SIP
DNS Address Support for SIP:
The IMG can route SIP traffic to a remote entity based on the IP Address or the Host Name. The IMG supports having multiple DNS servers for redundancy and reliability purposes.

SIP Privacy:
The IMG supports RFC 3325, which establishes a standard way to transport Calling Party identification information (CLI) between trusted networks, enabling a network of trusted SIP servers to assert the identity of end users and servers. External SIP gateways can be configured as either being Trusted or Untrusted for issues of privacy.
2 new headers are supported:
P-Asserted-Identity (Privacy ID)
Remote-Party-ID (Privacy Tag, Screen Tag)

SIP-to-SS7 ISUP Cause Code Mapping:
You can modify the default mapping between SS7 ANSI and SIP cause codes, which is defined by RFC3398.

SIP Comedia (Symmetric RTP)
This feature allows the passage of VoIP packets between endpoints when one (but not both) of the endpoints resides on a private network behind a NAT (Network Address Translation) device. The Connection-Oriented Media (Comedia) Enhancements for SIP allows the IMG to check the media source of incoming Realtime Transport Protocol (RTP) packets, and allows the endpoint to advertise its presence inside or outside of Network Address Translation (NAT). Using this enables symmetric NAT traversal by supporting the capability to modify and update an existing RTP session remote address and port.
