Prolog information

Example 1

This SIP call flow example is a SIP trunking scenario where a test call is made from a PSTN trunk user (705030) to a Call Centre Elite user (604020) through Avaya SBC.
Trunk User —> ostn-cm —> pstn-asm —> SBC —> cce-asm —> cce-cm —> CCE user
The following table contains the parameter field names and values for the various interfaces, profiles, and policy groups used in this call scenario.
Note:
The provisioning information in this table is a sample reference for examining call flows and might be incomplete.
