ASE Messaging Flow
For ASE and MAUUI interworking, if UUI was included in the incoming
IAM and was delivered to the terminating agent in the Q.931 SETUP
message, then MAUUI is invoked for this call. If the terminating agent
responds with a call clearing message with UUI which causes
tones/announcements to be applied to the originating agent, the UUI will not
be delivered to the originating agent. This is because the originating agent
already received an ANM message from the ASE functionality. In this case,
the ASE feature functionality caused an answer indication to be sent out
before an answer indication was received from the terminating agent. The
following diagram shows an example of this interworking.
