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 applying the
iDCS 100 ITM3 VoIP feature. Network congestion does 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 re-
stricted. 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.
