6.5.32 Unrecognised Message Request
Note: This message is only applicable to ITU-T operation.
This primitive is used by the application to allow a message that is not known
to the ISUP module to be transmitted to the network. It may be useful in the
case that a national variant requires transmission of an additional message
type.
The ISUP module performs no checks on the contents of the message and
providing that a call is active will send the message directly to the network.
Message type
Unrecognised message
Mandatory parameters
Message data
Optional parameters
None
6.5.33 User Information Request
Note: This message is only applicable to ITU-T operation.
This primitive is used by the application to transfer user information to the
remote party during call set-up (supplementary service 2) or during the
established (speech) phase of a call (supplementary service 3). If the
corresponding supplementary service has not been requested and
subsequently accepted, this primitive will be discarded.
Note: It is only possible to exchange two user to user messages in each directions (i.e. 4
messages in all) for the supplementary service 2.
Message type
USR (User Information Message)
Mandatory parameters
User to user information
Optional parameters
