CHAPTER 3
Provisioning the Cisco HSI
Introduction
This chapter describes the data that must be provisioned for the Cisco H.323 Signaling Interface (HSI).
The data is divided into two areas: system configuration and H.323 stack data. This chapter contains the
following sections:
• Cisco HSI Configuration, page 3-1
H.323 Stack Configuration, page 3-10
HSI Feature Configuration, page 3-22
Cisco HSI Configuration
All configuration data is contained within configuration files. Cisco HSI starts

Chapter 3 Provisioning the Cisco HSI Cisco HSI Configuration HSI starts up, it attempts to read the active configuration, checks that the configuration has been verified, and ensures that the checksum matches. If the active configuration is not verified or if the checksum is faulty, the configuration reverts to using the $GWHOME/currentGW/etc/GWmain.conf file. All configuration data that can be set in the system is defined in the Skeleton Configuration file (see Appendix B, “Skeleton Con

The following MML command examples show how to enable DTMF capability on the HSI. (For a description of the sys_config_static entry and the dtmf parameters, please see the section (System Configuration Data).

Chapter 3 Provisioning the Cisco HSI Cisco HSI Configuration Dynamic System Data To modify the dynamic system data parameters in Table 3-4, use the sys_config_dynamic MML name variable for the prov-add, prov-dlt, and prov-ed commands. You need not halt and restart call processing for the changes to take effect. In the following example, the prov-add command adds the dynamic system data parameter OVLDLEVEL1PERCENT to a dynamic configuration file. The prov-ed command modifies the value of

This parameter is used in conjunction with the OVLDLEVEL1FILTER parameter. The overload level 1 value is the lowest level of overload and must be less than or equal to the provisioned values for OVLDLEVEL2PERCENT and OVLDLEVEL3PERCENT. N

Start means that the application needs to be restarted for the change to take effect. Next Call means that the next call has the new parameter set. Note Immediate and Next Call update types refer to dynamic system

Chapter 3 Provisioning the Cisco HSI H.323 Stack Configuration RAS Parameters The parameters in Table 3-8 are required for RAS stack initialization. To modify the RAS parameters, use the ras MML name variable for the prov-add, prov-dlt, and prov-ed commands. In the following example, the prov-add command sets the RAS parameter maxfail to the value 3. Example prov-add:name=ras,maxfail=3 The array index [i] in some of the parameter names in the first column of Table 3-8 must be replaced wi

Chapter 3 Provisioning the Cisco HSI H.323 Stack Configuration Codec Selection The Cisco HSI negotiates the media stream codec to establish a match between the PSTN MGCP media gateway (for example, the Cisco AS5xxx series or Cisco MGX series) and the H.323 endpoint or gateway. To match codecs, the MGCP gateway must be configured to match what is expected at the H.323 end. Similarly, the Cisco HSI also must be configured with the same codecs. The Cisco HSI receives a list of codecs from t
