Cisco Cisco Unified Customer Voice Portal 10.5(1)

To install the Call Survivability script, perform the following steps:

Copy the following files from the CVP application server machine to flash memory on the gateway:  

If using a CSS in the topology, copy all files under 
C:\Cisco\ISN\ApplicationServer\Downloads\VB-CSS-noCallRestart 

If not using a CSS in the topology, copy all files under 
C:\Cisco\ISN\ApplicationServer\Downloads\VB-noCSS-noCallRestart

On the gateway, define two applications as follows: 

See the 

section below for more details on 

configuration options.

call application voice somename flash:survivability.tcl

call application voice somename language 0 en

call application voice somename set-location en 0 flash:

call application voice handoff flash:handoff.tcl

call application voice handoff language 0 en

call application voice handoff set-location en 0 flash:

On the gateway, do a "call load application voice somename" and "call load application voice handoff"

Create at least one CVP pots dial-peer on the gateway, placing the CVP called number on an 
incoming-called-number parameter. Assign the somename application to this dial-peer.

The recovery functionality in this script functions best when the SetTransferLabel command in CVP 
Voice Browser VBAdmin is activated. 

There are several parameters that can be configured on the gateway:

open-hours-agent - The destination recovery target DNIS to be used when the currenttime matches 
any open-hours-time parameter. The script will cycle through all agents sequentially until one 
answers. If no one answers, (or in the case of a takeback transfer, the PSTN does not take back the 
call), the script cycles through all after-hours-agent's (maximum of 50 agents).

Syntax: open-hours-agentX dnis

Arguments: X    = a number from 0 to 49, dnis = target destination for the recovery transfer.

Example 1: DTMF*8,9875551212 (When PSTN *8 takeback is desired)

Example 2: 9875551212 (when hairpin or SRST transfer is desired) where:

DTMF - indicates takeback and transfer via DTMF tones

*8 - the sequence the switch recognizes to perform the takeback. 

Zero or more commas - each comma represents a pause of 100 ms. Some switches require a 
pause between the takeback sequence and the DNIS.
