AltiGen MAXCS 7.0 Update 1 ACM Administration - Manual (Page 333)

Assigning Codec Profiles to IP Addresses
MaxCS 7.5 Administration Manual 317
The G.722 codec is supported in HMCP media servers only. AltiGen's telephony boards, including the Triton
and Vision boards and the Max1000 and Max2000 boards, do not support the G.722 codec.
G.722 is supported by the following devices:
• AltiGen IP 805 phone - G.722 64 kbps ONLY
• Polycom phones
• SoundPoint IP-335, IP-550, IP-560, IP-650, IP-670
• SoundStation IP-6000, IP-7000
• VVX 300, VVX 310, VVX 400, VVX 410, VVX500, VVX 600
• SIP tie trunks
The G.722 codec is part of combo codec and is controlled by license.
Note: When adding additional combo licenses, the system will also increase the RTP ports it uses and will
use these new ports. If these additional ports are not added to the firewall, then calls will not have
audio.
The number of total codecs is shown in the License Information panel.

Assigning Codec Profiles to IP Addresses
You can specify what codec profile to use when connecting to the following VoIP devices:
• IP phones on the LAN
• a remote IP phone over WAN
• a remote AltiGen system over WAN
• SIP Trunk service provider over WAN
• multiple gateways on the LAN
The codec profile assigned in the IP Device Range table (shown below) supersedes the codec profile defined
in the IP dialing table if the IP address is duplicated in both tables.
The SIP transport assigned to an extension in the IP Phone Configuration screen takes precedence over a
codec profile with a different SIP transport assigned in Enterprise Manager. If the IP extension supports TLS
and the codec profile does not, then the IP extension policy holds. That way you can configure a range of IP
addresses in the IP dialing table or IP codec, and have only a few IP addresses/extensions support TLS.
If the IP extension has not configured TLS as its transport, and the codec profile supports it, then the codec
profile policy holds.
To set IP address ranges and assign codec profiles to them, in Enterprise Manager, on the Servers tab, click
the IP Codec sub-tab.
