Specifications

In any Ethernet environment, packet transfers are subject to delays and/or loss. If these delays are greater
than 200ms the voice quality will deteriorate. The Ethernet data traffic and network topology should be a
consideration when using VoIP. Network congestion will affect call quality in any VoIP application.
WALKING CLASS OF SERVICE
This feature allows users to make calls or use features from a station that is restricted. The users may either
use the WCOS feature code or the authorization code feature. Both methods change the class of service to
correspond with the station passcode or authorization code that is dialed. After the call is completed, the sta-
tion returns to its programmed class of service.
