Cisco Systems 1.4 Manual De Usuario

You configure interceptor port error handling to tell Cisco CallManager how to route calls to 
Personal Assistant users when the Personal Assistant server is unavailable. If you do not configure 
interceptor port error handling, and if Personal Assistant is unavailable, a user phone will not ring when 
called, and the caller will hear a fast busy tone.

The way you configure interceptor port error handling differs according to which version of 
Cisco CallManager you are using, as follows.

If you are using Cisco CallManager version 3.x, when you create an interceptor port, you create two 
entities: a route point, and a translation pattern. Cisco CallManager uses the translation pattern for error 
handling. Each translation pattern must match the set of numbers in the corresponding interceptor port 
route point. The translation patterns must not be placed in the PA partition, as this could cause a match 
even when the Personal Assistant server is available.

If you are using Cisco CallManager version 4.0 or later, you configure interceptor port error handling by 
setting the Forward No Answer destination and calling search space to the same values as the directory 
number configured for the interceptor CTI route point.

Personal Assistant provides users with the ability to access their voice mail, to call other users by using 
speech commands, and to configure rules for handling incoming calls. If you choose not to use some of 
these features, the following sections can assist you in determining what you need to do:

You can use Personal Assistant without using the speech-recognition capability. Without speech 
recognition, your users can interact with Personal Assistant only by using the touch-tone interface. Thus, 
instead of talking to Personal Assistant, the user must learn the key sequences required to navigate 
through voice mail, and they must spell out names using the keypad.

If you do not want to use speech recognition, do not install speech-recognition servers.

If you do not allow Personal Assistant to intercept incoming calls, you can use Personal Assistant 
without rule-based call routing. Without rule-based call routing, your users cannot have 
Personal Assistant intercept and handle their incoming calls. 

If you do not want to use rule-based call routing, do not configure partitions and calling search spaces 
in Cisco CallManager. You also do not need to configure intercept ports. However, if you use speech 
recognition, you must configure the CTI route point and media ports in Cisco CallManager.
