Advanced Operational Features

Single Call Restriction (57i CT only)

On the 57i CT, an administrator can enable or disable a single call restriction between the 57i CT base unit and a call server.

When this feature is enabled (set to 1), you can make separate active calls from the 57i 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.
