Prerequisites
Requirements
Cisco recommends that you have knowledge of these topics:
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Problem
In a call studio application, like for example Courtesy Callback (CallbackEntry), the system record the name of the caller for 32 sec where as in call studio application in the audio node property it is set as max record time as 180 sec.
Troubleshoot
Step 1. Enable VXML gateway logs.
debug vxml application all (lab environment only)
Step 2. Collect Activity logs from the applicaton, located on C:\Cisco\CVP\VXMLServer\Applications\{application}\Logs\ActivityLog\
From the activity logs you can see that the Record element sarts:

Solution
In the VXML gateway, Increase the IVR record memory session with this command.
gw(config)#ivr record memory session? <0-256000> memory in Kbytes
