Configuring Mitel 3300 for Spitfire SIP Trunks

This document is a guideline for configuring Spitfire SIP trunks onto Mitel 3300 and includes the settings required for Inbound DDI routing and Outbound CLI presentation. The settings contained within have been tested and are known to work at the time of testing. SIP trunk details such as account number and password will be provided separately.

Provisioning a SIP trunk: Page 2 Inbound Routing – Reference only: Page 8 Outbound Routing – Reference only: Page 9 Outgoing CLI – Reference only: Page 10 As there are several ways to program Inbound/Outbound routing on the Mitel 3300, the Inbound/Outbound routing examples are intended as a reference only. System installers may program differently according to their requirements.
