Intel PROSet/Wireless software supports VoIP third-party soft-phone applications.
Third party VoIP applications support Voice Codecs. Codecs are used to encode voice for
transmission across IP networks. Codecs generally provide a compression capability to save
network bandwidth.
Intel PROSet/Wireless software supports the following International Telecommunications Union
(ITU) codec standards:

G.711
PCM (Pulse Code Modulation) 64 G.711 with mu-law used in
North America and Japan,
while G.711 with A-law used
in the rest of the world.

An administrator can create profiles that use pre-existing VoIP profiles to configure various
codec data rates and frame rates to improve voice quality in VoIP transmissions.
To create a VoIP profile:
NOTE: Ensure
Voice over IP is not disabled in the Administrator Tool Application
Settings. It is enabled by default.
1. Click Include Profiles.
2. Select a profile from the list.
3. Click Properties to open the Create VoIP Profiles page.
4. Select the Codec bandwidth, application usage and Frame Rate.
