17.1 Accessibility and Voice Quality
The base network is not always available. If you do not get in contact with your system,
contact your system administrator.
For various reasons, some functionality in the system may be inaccessible, causing various
status texts to appear.
No System
When you leave the system
'
s coverage area the text “No System” will appear in the
display. Additionally, a parameter can be set to enable a short beep to sound when the
message is shown.
Note:
When re-entering the coverage area it can take a couple of minutes before the
handset automatically has registered into the system.
It is also possible to get an out of coverage warning signal by setting a flash memory
parameter.
No Access
If the handset has found the system but for some reason cannot connect to it, the text
“No Access” is shown.
Voice Only
If the handset is unable to connect to the IMS, messaging will not be available and the text
“Voice Only” will be shown.
Messaging Only
If the handset is unable to connect to the gateway, voice calling will not be available and
the text “Messaging Only” will be shown.
17.2 Error Codes
When the base network is available a call may sometimes still fail. In such cases, the error
code shown indicates the reason for the failed call.
No response
The called portable is unavailable “not registered”. The error code can also appear the first
two minutes a called handset is out of coverage or if the battery is removed without
turning the handset off.
No Channel Available
The connection fails because no appropriate channel is available to take the call. For
example when a handset is designed for two simultaneous calls and a user tries to make a
third call. Another cause can be that the handset has lost contact with the VoIP Gateway.
