Introduction
This document describes the IVR−Based Outbound Dialer and includes a sample SIP gateway configuration,
log analyses from both the SIP gateway and the Cisco Unified Contact Center Express (UCCX) engine, and
the limitations of the IVR−Based Outbound Dialer.
In UCCX 8.5, a new type of outbound dialer was introduced: the Interactive Voice Response (IVR)−Based
Outbound Dialer. Unlike the older Preview Outbound Dialer, no agent is used to make the outbound call.
UCCX connects directly to a Session Initiation Protocol (SIP) gateway in the customer enterprise to dial the
outbound contacts. When the gateway detects a live voice or answering machine, the call is redirected to a
UCCX trigger bound to an outbound call control group. Once terminated on the outbound computer telephony
integration (CTI) port, the application associated with the trigger is executed as normal.
Feature Information
In UCCX versions earlier than 8.5, only the Preview Outbound Dialer existed. This dialer used third−party
call control via Java Telephony Application Programming Interface (JTAPI)/CTI to instruct the agent's phone
to make the call. The call was made after an agent accepted an outbound reservation. The interaction between
the client and server for outbound reservations was accomplished via CTI.
For certain use cases (such as appointment reminders and self−service IVR applications), the Preview
Outbound Dialer was not a good fit. To make a call to a number in the DialingList, an agent was tied up while
the call was placed. That meant the agent was occupied for each and every outbound call, even if the Public
Switched Telephony Network (PSTN) number was invalid, busy or resulted in an answering machine. This
