480i CT Only
Single Call Restriction (480i CT only)
A new feature has been implemented on the 480i CT that allows an administrator 
to enable or disable a single call restriction between the 480i CT base unit and a 
call server.
When this feature is enabled (set to 1), you can make separate active calls from 
the 480i CT base unit and from the cordless handset. If this feature is disabled (set 
to 0), only one call can be active at a time either from the base unit or from the 
handset. When this feature is disabled, and you make an active call on either the 
base unit or the handset, any other attempt to make an active call is put on hold. 
Also, when this feature is disabled, more than one call can negotiate complex 
audio codecs since only a single call is decoding audio at a time.
You can configure this feature via the configuration files or the Aastra Web UI.
