Configure Voice over IP for Microsoft NetMeeting
Voice over IP for the Cisco AS5300 37
Configure CODEC for a VoIP Dial Peer
To specify a voice coder rate for a selected VoIP peer, use the following commands beginning in
global configuration mode:
The default for the codec command is g729r8; normally the default configuration for this command
is the most desirable. If, however, you are operating on a high bandwidth network and voice quality
is of the highest importance, you should configure the codec command for G711 A Law or
G711 U Law. Using either of these values will result in better voice quality, but it will also require
higher bandwidth requirements for voice.
For example, to specify a CODEC rate of G.711A Law for VoIP dial peer 108, enter the following:
dial-peer voice 108 voip
destination-pattern +1408528
codec g711alaw
session target ipv4:10.0.0.8
Configure VAD for a VoIP Dial Peer
To disable the transmission of silence packets for a selected VoIP peer, use the following commands
beginning in global configuration mode:
The default for the vad command is enabled; normally the default configuration for this command
is the most desirable. If you are operating on a high bandwidth network and voice quality is of the
highest importance, you should disable vad. Disabling VAD will result in better voice quality, but it
will also require higher bandwidth requirements for voice.
For example, to enable VAD for VoIP dial peer 108, enter the following:
dial-peer voice 108 voip
destination-pattern +1408528
vad
session target ipv4:10.0.0.8
Configure Voice over IP for Microsoft NetMeeting
Voice over IP can be used with Microsoft NetMeeting (Version 2.x) when the Cisco AS5300 is used
as the voice gateway. Use the latest version of DirectX drivers from Microsoft on your PC to improve
the voice quality of NetMeeting.
