Addresses
In this menu, you can enable/disable automatic assignment of an IP address (Automatic IP address), or
insert manually:
•
IP Address;
•
SubNet Mask;
•
Gateway IP Address ;
•
DNS Server IP Address.
Dynamic Ports
The range of the TCP and UDP (*) “Dynamic Ports” can be found automatically (Auto detect) or set
manually (default: TCP-3230; UDP-3230).
Note (*):
When a firewall is crossed, the firewall administrator must open a range of dynamic TCP
and UDP ports, as configured in the system, to allow bidirectional IP traffic. Moreover,
once the ports have been opened, the protocols (TCP 1720 (Q.931), TCP 1503 (T.120), UDP
1719, and 1718 (RAS)) involved in a call must be taken into account.
NAT
In default “Use NAT” is already selected, and the following parameters can be set:
a) “NAT Type”;
b) “Public IP Address” must be the public IP address of the NAT;
c) “Refresh Time”.
QoS
It is possible to choose the policy regarding “Quality of Service” (QoS) by choosing between
Precedence/TOS and Service Diff.
Bandwidth
If the function is “Activated” it is possible to set maximum limits for the use of bandwidth (in Kbps). These
limits can be different for reception and transmission.
