Introduction

The sections that follow describe Natural Access parameters (parameters in the cta.cfg file) that determine MGCP service behavior.
All parameters appear in the [ctapar] section of the mgccta.cfg file according to the following format:
MGC.category.parameter = value
Where category is one of the categories of parameters described in this Appendix, and parameter is a one of the strings that appears in the table provided for each category.
For example: MGC.General.GatewayDomainName = "mg1.com:2427" MGC.General.DTMFDuration = 0 MGC.General.AnnPath = "//opt//nms//fusion//mgcp//" Note: To MGCP modify MGCP paramter default values, modify the mgcparm.h file.
The following categories of MGCP Natural Access configuration file parameters are editable:

Caution:

Most of the parameters that follow are signaling-specific: changing their value will invalidate any approval certificate for the used board, and may cause the board to malfunction. These parameters are described here for reference purposes only.

Call Waiting Tones

The call waiting tone is defined in GR-506-CORE, 14.2, and the call waiting feature is defined in TR-TSY-000571. According to the ITU, a call waiting tone is a tone advising the user of the call waiting supplementary service. That is, the tone informs a caller that is engaged on a call that someone is attempting to call the number.
The MGCP service supports four different call waiting tone patterns (refer to GR-506-CORE, 14.2) that are defined by wt1, wt2, wt3, and wt4 parameters.
