CS1 INAP Uncharged Call With Announcements

The following two example message sequences are for uncharged CS1 INAP calls for which CCF instructs an internal or external IVR to play pre-call announcements.

Figure 1 shows the message sequence used when MATRIXX Engine determines that the CS1 INAP call is free, and returns a PlayAnnouncement request to play pre-call announcements on the internal IVR. The EventTypeBCSM parameter in the InitialDP is set to 2 (collectedInfo).
