Prerequisites

Following are the basic prerequisite for enabling TSS:

TDM-based Remote Extension

When TDM-based remote extension is configured:

  • When calls are made to the remote extension, the remote device rings and is able to answer.
  • The remote device is able to call R1/2/3 numbers and will be validated as the remote extension number.
  • Received A-number and the configured remote number must be the same. The remote number must be the same as the numbers configured in conversion Table 1. For the remote number to be vali- dated against the received A-number, which is the number programmed in the number conversion Table 1, the received A-number might first need to be converted as per conversion type 2 (see Example 1 − Remote Number, International Number Type).

SIP Remote Extension

When SIP remote extension is configured:

  • When calls are made to the remote extension, the remote device rings and is able to answer the calls.
  • Remote device is able to call R1/2/3 numbers and will be validated as the remote extension number.
  • Received A-number and the configured remote number must be the same. That is, the remote number must match the numbers configured in conversion Table 1. For the remote number to be validated against the received A-number, which is the number programmed in the number conversion Table 2, the received A-number might first need to be converted as per conversion type 2 (see Example 1 − Remote Number, International Number Type and Example 2 − Remote Number, International Number Type).

CSTA Configuration

The CSTA server phase III interface must be configured and active, and the CSTA authentication configured. For more information, see the CSTA Server (Phase III), Operational Directions.

Aids
