Four of the six modes are automatic (AUTO 1 - AUTO 4), another one is manual (MANUAL -
ROUTER CONFIG) and the last one (OFF - LOCAL NETWORK) is used when no devices with
NAT are crossed (the unit is in a local network or connected to the Internet with a single
workstation router). In automatic modes the unit tries to find out its public IP and ports without
the user help, while in manual mode the unit gets those data directly from user (and user gets it
from network administrator).
NAT TRAVERSAL options menu detail
Detailed descriptions are given below of the working modes supported by Phoenix STRATOS:
• OFF (LOCAL NETWORK): 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).
Mode OFF selection detail
• MANUAL (ROUTER CONFIG.): This mode will be used when the Phoenix STRATOS
is in a local network with shared Internet access, through a router that will work as NAT
(Netword 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).
Mode MANUAL selection detail
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 STRATOS units through Internet. Complex scenario configuration. Through
LOCAL network(s), DHCP not used, manual NAT. Making use of AEQ Proxy SIP).
The eight configuration parameters available on screen 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 172.26.5.59. It can be set
in order to adapt it to network necessities in menu / SYSTEM / 8.SETTINGS /
