PictureTel LIVE GATEWAY 3.1 - Manual (Page 49)

2. If no tones are received within 30 seconds, the call is routed to the H.323 client designated as the
operator station. If an H.323 Terminal that supports call transfer, such as LiveLAN, is being used as the
operator station, an operator (person) asks for the name or H.323 Terminal ID, and then transfers the call
normally. If an operator station is not specified, the call is disconnected.
Note: Any PictureTel LiveLAN Terminal can be designated as an operator station. Other H.323
terminals, however, may not support this function.
Operator-assisted Calls
When a LiveLAN client is designated as an operator station, LiveGateway directs incoming calls requiring
operator assistance to that station. Calls without DTMF are examples of calls that require operator assistance.
To designate a LiveLAN client as an operator station, the LiveManager administrator must enter the H.323
Terminal ID of the client into the LiveManager operator station mapping file.
When an incoming H.320 call requires operator assistance, LiveGateway uses the information in the
LiveManager mapping file to pass the call to the operator station. From there, the operator transfers the call
using LiveLAN’s call transfer capability. For more information, refer to the PictureTel LiveManager Product
Guide.
If an operator station is not specified in the LiveManager operator station mapping file, the call will be
disconnected if:
• The H.320 terminal does not have DTMF capability.
• The H.320 terminal has DTMF capability, but the caller does not know the destination H.323 Terminal
ID.
• An incorrect H.323 Terminal ID is entered.
The "Always Use Operator Station" Feature
You can configure LiveGateway to use the Operator Station to answer all incoming LiveGateway calls by
enabling the "Always Use Operator Station" checkbox on the LiveGateway Configuration utility window when
you install LiveGateway. The feature is enabled when a checkmark appears in the checkbox. The system default
for this feature is set to disabled. Click on it to enable it. Refer to
Running the LiveGateway Configuration
Utility for specific information on how to change LiveGateway board configuration information.
Sample Configuration
The following diagram shows a sample configuration consisting of an ISDN WAN, a LiveGateway, LiveLAN
clients, and an H.320 client.
