Isdn Incoming Call, November 320 | Dialogic 6.2 manual

ISDN Call Processing Overview

It is also possible to configure BSMI to generate a SETUP_ACK rather than a CALL_PROCEEDING message upon arrival of a setup message.

Figure 48. ISDN Incoming Call

As in the case of a call, BSMI also handles the call model where a SETUP_ACK generated instead of a call proceeding.
