2.Peer-to-Peer
Before calling, you have to know your friend's IP Address. The Vigor
VoIP Routers will build connection between each other. Please refer to
the Example 3 in the 4.3 Calling Scenario.
Our Vigor2100 V models firstly apply efficient codecs designed to make
the best use of available bandwidth, but Vigor2100 V models also equip
with automatic QoS assurance. QoS Assurance assists to assign
high priority to voice traffic via Internet. You will always have the
required inbound and outbound bandwidth that is prioritized exclusively
for Voice traffic over Internet but you just get your data a little slower and
it is tolerable for data traffic.
