VoIP QoS

VoIP QoS is a function that allows users to keep enough bandwidth for VoIP calls during

heavy Internet usage periods; hence it can maintain high-quality VoIP calls.

Conditions of QoS

There are two conditions to use the V200 QoS feature properly.

Firstly, your broadband Internet connection should have a ﬁxed upstream bandwidth. Cable

broadband Internet services share a ﬁxed bandwidth and therefore do not have a ﬁxed

upstream bandwidth for their Internet access. In contrast, ADSL users normally have a ﬁxed

upstream bandwidth, which should be stated in their ADSL service plan contract.

Secondly, you will need to let your V200 to handle the Internet trafﬁc for your LAN

network. We recommend you install your V200 based on the following network diagram

which will let the V200 QoS work properly. If you have already had an ADSL router

working, you will need to reconﬁgure your ADSL router into bridge mode in order to use the

QoS feature (Please refer to the User Manual of your ADSL modem/router for instructions

on how to set this up).

Note:

The WAN port mode in this diagram can be either in PPPoE or Static IP

(assign a public IP) mode.
