Chapter 5. Configuring System Parameters and Dial Plans
This chapter covers the technician’s GUI screens. As with Chapter 4, this is a tour of the screens showing the structure and meaning of the different form fields. Unlike the users, the servers are provisioned automatically by the make allinone script, and the GUI screen lets you edit the provisioned data if necessary. Chapter 3 provides instructions about deploying VOCAL onto a multihost system with redundant servers.
The technician’s screens are divided into system and server settings. The system settings provide access to some general system parameters and the dial plans. This chapter offers mostly description and only a few procedural instructions. We encourage you to play around with using the different fields.
The dial plans are initially empty and require some knowledge of regular expressions to make them work. We have provided some examples in this chapter with a general discussion about how dial plans work with SIP messages in VOCAL.
The servers folder also provides a screen for configuring the Open Settlement Protocol (OSP) server. At the time this is being written, few in the SIP community were seriously using OSP for anything except laboratory testing, although recently we have seen some renewed interest in the mailing lists. The user community has yet to grow to the stage at which OSP is widely used for brokering costs between managed IP networks. The concepts behind OSP are discussed in Chapter 18.
