2. Select to go to the Preferred Speeds screens and configure these
settings:
3. Select to go to the Call Speeds screen and specify the call speeds to
make available to users, if you are allowing them to choose speeds on a
call-by-call basis.
Configuring Dialing Order Settings
If the call type on the home screen is set to a specific call type, the system does
not attempt to place the call using a different call type, even if other types are
listed in the Dialing Order.
You can configure the VSX system so that users can choose to place IP-to-ISDN
or ISDN-to-IP calls through a gateway.
To allow users to place an IP-to-ISDN call through a gateway:
1. Make sure the system is registered with a gatekeeper.
2. Go to System > Admin Settings > Network > Call Preference and select
Enable ISDN Gateway.
3. If you want to allow users to place IP-to-ISDN calls through a gateway
when calling from the directory, do one of the following:
— On the Network Dialing screen, set Preferred Dialing Method to
Auto and select ISDN Gateway as the first choice under Dialing
Order. With this configuration, calls placed from the directory will be
placed through a gateway first if an ISDN number exists.
— On the Network Dialing screen, set Preferred Dialing Method to
Manual. With this configuration, users can select ISDN Gateway
from the list of call types that appears when placing a call from the
directory.
Setting Description
Preferred Speed
for Placing Calls
Determines the speeds that will be used for calls from this
system when:
• Call Quality is set to Auto on the home screen and
Directory screen, or
• The Call Quality setting is not available for users.
If the far-site system does not support the selected speed, the
system automatically negotiates a lower speed.
Maximum Speed
for Receiving
Calls
Allows you to restrict the bandwidth used when receiving
calls.
If the far site attempts to call the system at a higher speed
than selected here, the call is re-negotiated at the speed
specified in this field.
