6.5.15 Information Request
This primitive is used by the application to submit additional call information
to the network and may take two forms.
Subsequent Address Digits
Note: This message is only applicable to ITU-T operation
This message may be used to convey subsequent outgoing call called party
number address digits to the network when overlap signaling is employed. It
is not used for ANSI operation.

Optional parameters
None
Additional call information

simple segmentation procedures whereby including this additional information
in an Initial Address Message would cause the message to be over length.
Message type
INF (Information Message)
