19-20 MAUUI
Figure 19-21
Suppcode/Digit Collection Example
For the previous example showing call message flow, if UUI is included in
the call setup message and it is delivered to the terminating agent in the call
setup message, MAUUI is invoked for the 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 is
delivered to the originating agent in an ISUP CPG/Q.931 Progress message.
In this case, the Digit collection causes the ACM to be sent to the originating
agent, independent of whether the terminator sends an alerting indication or
not. The following figure shows an example of digit collection with MAUUI
interworking.
