Cisco Systems 1.4 Manual De Usuario

Choose a server, for example the MCS-7835-H1-IPC1.

Determine how to install the Personal Assistant components, for example, whether you want the 
Personal Assistant server and speech-recognition servers on separate systems.

Determine how many sessions you must support for your users:

1750 users divided by 25 = 70 call-interception sessions

1750 users divided by 50 = 35 speech-recognition sessions

You need enough servers to support at least this number of sessions. When you configure the servers, 
you specify the actual number of ports in use, so if you intend to use fewer than the maximum, take 
this into consideration when determining the number of servers that you need.

Use the information in 

 to determine that if you install the Personal Assistant server and 

the speech-recognition server on separate MCS-7835-H1-IPC1 systems (for a total of two systems) 
you can support:

70 call-interception sessions

36 speech-recognition sessions

Therefore, you can support 1750 users by using two MCS-7835-H1-IPC1 systems: one system for 
the Personal Assistant server and one system for the speech-recognition server.

Be sure to add the servers by using the Personal Assistant administrative interface:

Add the speech-recognition servers to the System Configuration settings. See the 

.

Add the Personal Assistant servers to the Server Configuration settings. See the 

.

You also must add the number of supported ports by using the Personal Assistant administrative 
interface:

Add the supported number of media ports in the Server Configuration settings. See the 

. Although your selected server 

configuration supports up to 36 ports, you only need 35 ports for your users.

Add the interceptor port addresses in Server Configuration settings. See the 

. In this setting, enter the interceptor ports that 

cover all 1750 users. Although your configuration supports 70 simultaneous sessions, the 
interceptor ports must cover all users you are supporting.

Consider configuring load balancing (see the 

) or adding failover servers (see the 

) for greater redundancy.

A single Personal Assistant server can handle a number of simultaneous sessions, which you define 
when you set the number of media ports (see the 

). When 

all media ports are being used, new callers receive a busy signal from Personal Assistant unless you set 
up load balancing among the Personal Assistant servers in each Personal Assistant server cluster.

If you are not using failover servers, and if a Personal Assistant server becomes disabled, no other server 
takes over the media ports of the disabled server. This reduces the number of available simultaneous 
sessions with Personal Assistant. However, you can set up load balancing in the cluster to mitigate the 
effects of a disabled server.
