Call handlers answer calls, greet callers with recorded prompts,
provide them with information and options, route calls, and take messages. They
are a basic component of Cisco Unity. Your plan for call handlers can be
simple, with only the predefined Cisco Unity call handlers, or you can create
an unlimited number of new call handlers.
This document explains the recommended workaround for the problem you
can face when you attempt to add a call handler to a CiscoUnity server through
Cisco recommends that you have knowledge of Cisco Unity.
The information in this document is based on the Cisco Unity 4.x.
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.

When you attempt to add a call handler to a Cisco Unity server with
more than 1,000 existing call handlers, an ASP script time out occurs after
ninety (90) seconds.
When you attempt to add a call handler, Cisco Unity queries the
Microsoft SQL database for exisiting call handlers and their attributes. On a
Cisco Unity server with more than 1,000 existing call handlers , this query
exceeds ninety (90) seconds and results in a ASP script time out. A dialog box
appears after you press the plus symbol in order to add a new call handler.
This box is initially transparent but transitions to solid white after ninety
(90) seconds have passed.
In order to overcome this problem:
Once you have 1,000 call handlers on your system, do not use the
Cisco Unity System Administrator to create additional ones. Instead, use the
Audio Text Manager in order to create call handlers.
Note: You can make use of Audio Text Manager in order to create and edit
complex call handlers whenever you have a problem with the Cisco Unity System
Administrator. Refer to
for more information and to download the Audio Text Manager
It can also be possible to increase the ASP Script timeout on the
App Options tab from a default value of 90 seconds to at least
300 seconds in the Internet Service Manager, under the
Default Web Site.
Note: If you adjust the IIS timeout settings, this can adversely impact
other Cisco Unity web components and the values suggested here possibly do not
work for your particular system.
