Codec Enhancements
Codec enhancements in Release 7.5 include the following features:
• G.722 Supported Devices/Interfaces
• G.722 License Information
• G.722 in HMCP Board Configuration
• G.722 in the Current Resource Statistics View
• Managing Codec Priorities
• Managing IP Network Bandwidth
• Codec Negotiation
• Codec Upgrades
• Codec Preference for Incoming SIP Trunk Calls
• Codec Preference for Outgoing SIP Trunk Calls
MAXCS 7.5 supports the G.722 codec (for Softswitch and Cloud deployments; G.722 is not supported on hardware
chassis deployments).
G.722 is a wideband audio codec that provides higher voice quality than more narrow-bandwidth codecs such as
G.711. MAXCS supports G.722 64 kbps only.
The CPU processing requirement for G.722 is similar to G.723 and G.729. It is designed to use the same combo
codec resources as G.723 and G.729.
Release 7.5 offers more flexible codec preference settings than earlier releases. Enterprise Manager converts your
existing codec configuration to new 7.5 codec profile settings. Because of this, after you upgrade to release 7.5,
you should review the converted codec settings and adjust them as needed.
G.722 Supported Devices/Interfaces
The G.722 codec is supported in HMCP media servers only. AltiGen’s telephony boards, including the Triton and
