For more information about Virtual Trunks, see IP Peer Networking
Installation and Commissioning (NN43001-313).
Virtual Trunks are sometimes referred to as H.323 IP Peer Trunks. In the
SRG200/400 Release 1.5 Configuration Guide, Virtual Trunks are referred to
as IP Trunks.
IP Phone calls
When an IP Phone calls another IP Phone, each telephone receives the
address of the other to exchange media directly between the telephones.
When in Normal Mode, an SRG IP Phone calling a main office IP Phone does
not require any trunking to set up the call. However, LAN/WAN bandwidth
is used to provide a media path for the call. For more information on Direct
IP media path functionality, see IP Peer Networking Installation and
Commissioning (NN43001-313).
For a complete overview of Bandwidth Management, see Converging the
Data Network with VoIP Fundamentals (NN43001-260), and for details on
configuration, see "Bandwidth Management" on
Network Bandwidth Management allows for a limit to be placed on the
amount of interzone bandwidth allowed between IP Phones in Normal Mode
at the SRG and the rest of the CS 1000 network.
As well, it allows for the selection of interzone bandwidth codecs for calls
between the IP Phones in Normal Mode and the rest of the CS 1000 network.
Adaptive Network Bandwidth Management allows the system to dynamically
react to Quality of Service (QoS) degradation and take corrective action.
