4.3.1 Call Server
In the Call Server area, select the geographically relevant Call Server. By dialing and receiving
calls, and by collecting and storing call record information, the Call Server facilitates both Mobile
Originated and Mobile Terminated call performance sequences.
The Allow client override of call server results option was implemented for a small group of
international customers facing an unreliable landline infrastructure. This option should be left
unchecked unless otherwise instructed by the Spirent Product Support Team.
