Info (on the SIP server)
The status of registration to the SIP server is displayed. If the handset is registered, the time until the
expiry of this registration is displayed. Shortly before the expiry a new registration will be carried out
automatically. If no registration was possible, the most recent SIP error code will be displayed.
The following codes are used for frequently occurring errors:
Status code 0
: There is no SIP signalization error; rather it is highly likely that there is a problem with
the network. This can be the case when e.g. the SIP server was not attainable or has not responded.
Status code 404 Not Found
: The user ID is unfamiliar to the registrar.
Status code 401 Unauthorized
: There was an error in authentication. An incorrect SIP password
could be the cause.

Roaming info
If this option is active, the handset will bring up an alert window each time a connection to an AP is
established, lost or changed. The message contains the BSSID of the AP. It will disappear automati-
cally after a few seconds. The message appears when the option is active irrespective of the opera-
tional status of the device, e.g. even during a conversation. This function can be used to detect
errors and weaknesses in an existing installation.

Info (on the network connection)
You receive information about the status and properties of the network connection:
IP address
: Own IP address, or “-” if none is available. The latter can be the case if DHCP is activated
and no address has yet been assigned.
Gateway
: IP address of the default gateway, “-” if none has been configured and/or has not been
assigned by DHCP.
MAC
: Own MAC address.
SSID
: If there is a connection to the WLAN, the corresponding SSID is displayed here.
BSSID
: MAC address of the AP that the device is currently associated with. “-” if there is no associa-
tion, i.e. no connection to the WLAN.
RSSI history
: In the diagram the progression of the destination field strength of the currently active
AP over the last few minutes is displayed. The perpendicular axis shows the field strength in dBm,
the horizontal axis shows the time. On the right-hand side the current field strength is displayed,
older field strengths are further to the left.
The green area of the diagram marks field strengths, which are suitable for telephony. Those in the
red area will be subject to restrictions (interference, interruptions).
Using the
softkey, the scale of the time axis can be changed between approx. 30 minutes
and approx. 5 minutes.
