Overview
Using the survivability.tcl script, CUBE can complement the Cisco Contact Center Enterprise solution with several unique features.
-
Courtesy Call Back: With the Cisco Voice Portal (CVP) application, a caller may request an automated callback, rather than wait in a queue for an extended period. When an agent becomes available, CVP sends a request to place a call to the original caller. When the call is answered, the agent is connected.
-
Contact Center Survivability: If there is a failure when connecting to an agent, the script takes control of the call and redirects it to a preconfigured destination. If the call cannot be redirected, a pre-recorded announcement from a local file is played out to the caller before disconnecting the call.
Before Cisco IOS XE Cupertino 17.9.1a, these features were only available for unencrypted PSTN trunks. From Cisco IOS XE Cupertino 17.9.1a, they may also be used with encrypted (SRTP) trunks.
