4.3.1. Operation without NAT: "OFF (there is no NAT)".
The unit uses no mechanism to traverse devices with NAT. This mode will be used only to
operate in the local network (all of the SIP participants are in the same local network, including
the Proxy SIP, if we use it).
4.3.2. Manual NAT: "MANUAL (router configuration)".
This mode will be used when the unit is connected to a local network with shared Internet
access, through a router that will work as NAT (Network Address Translation). In order to use
this mode no DHCP must be used and you need to have access to router configuration (and the
knowledge to do it) or to the Network Administrator that will give us some data to be configured
in the unit and configure the router to open and redirect some IPs and ports (port forwarding).
The procedure is described in detail in the following Application Note (we recommend you to
read it when you decide to use this working mode):
AEQ PHOENIX AUDIOCODECS. APPLICATION NOTE 0 - C
(Connecting AEQ Phoenix units through Internet. Complex scenario configuration. Through
LOCAL network(s), DHCP not used, manual NAT. Making use of AEQ Proxy SIP).
The eight parameters to be configured in the dialog for this mode are:
1. SIP LOCAL IP: read-only parameter that tells you the IP of the IP interface of the
unit as regards SIP, so that the latter can, in turn, convey this to the router or
firewall administrator when it is configured.
For instance
172.26.33.35
. It can be set
in order to adapt it to network necessities in menu: "Configuration"
"Ethernet".
