CS context configuration task list 341
SmartWare Software Configuration Guide 31 • CS context overview
The CS context and its associated components route and establish voice calls. For example, the signaling for
dial-up circuits is routed and the corresponding voice call circuits are switched between PSTN interfaces and
via VoIP interfaces to the VoIP gateways and the IP context (see section “Configuring call routing” on
page 345 for more details).
CS context configuration task list
Information needed for CS entity configuration is distributed among several configuration tasks, depending on
its logical content. For example, information pertaining to call routing is described in section “Configuring call
routing” on page 345. These configuration tasks can be described in other chapters; thus, to configure call
routing you have to refer to chapter 33, “CS interface configuration” on page 381 and chapter 40, “Call router
configuration” on page 456.
This chapter shows you the relationship between the CS configuration components. We recommend that you
perform the CS context configuration in the sequence described below. Many of the parameters have default
values that do not need to be changed, which means that you do have to modify all of the described configura-
tion tasks. In such cases it is stated in the text that you can skip the optional configuration task.
1. Planning the CS configuration
2. Configuring general CS settings
3. Configuring call routing
4. Configuring dial tones (advanced)
5. Configuring voice over IP settings (advanced)
6. Configuring ISDN ports
7. Configuring FXS ports
8. Configuring a H.323 VoIP connection
9. Configuring a SIP VoIP connection
10. Activating the CS context configuration
Planning the CS configuration
There are many policies and factors that can influence the CS context configuration. It depends on what your
application is and how your network is configured. Several factors to consider for planning your CS configura-
tion are listed below:
• Application/network scenario
• Peripheral devices, such as PBX or remote VoIP gateway.
• VoIP protocol
• Number and type of physical telephony ports available
• Call routing
