Configuring Mitel 3300 forSpitfire SIP TrunksThis document is a guideline for configuring Spitfire SIP trunks onto Mitel 3300 and includes the settingsrequired for Inbound DDI routing and Outbound CLI presentation. The settings contained within havebeen 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 2Inbound Routing – Reference only:Page 8Outbound Routing – Reference only:Page 9Outgoing CLI – Reference only:Page 10As there are several ways to program Inbound/Outbound routing on the Mitel 3300, the Inbound/Outbound routingexamples are intended as a reference only. System installers may program differently according to theirrequirements.

Provisioning a SIP TrunkLog into Mitel system administrationGo to Voice Network è Network Elements & select AddChange the Type to “Other”Check the SIP Peer2

Signaling and Header Manipulation Options:1.Change Use P-Asserted Identity Header to “Yes”Timers:1.2.The Registration Period may be a minimum of 300, maximum of 3600Change the Session Timer to “0”Save the SIP trunk7

Inbound DDI Routing – Reference onlyGo to Trunks è SIP è SIP Peer Profile Assignment by Incoming DID & select Add1.2.Enter the Incoming DID Range as supplied by Spitfire. You can wildcard if you wish.Assign the Spitfire SIP Peer in the SIP Peer Profile LabelGo to System Properties è System Feature Settings è System Speed Calls1.2.Enter the remainder digits (i.e. what remains after the absorption in your Trunk Attribute ServiceNumber – Page 4) of the Incoming DID in the Speed Call NumberEnter the extension number you wish to route the DID to in the Actual Number8

Outbound Routing – Reference onlyGo to Call Routing è Automatic Route Selection (ARS) è ARS Routes and select a route to modify.1.2.3.Select “SIP Trunk” for the Routing MediumChange the SIP Peer Profile to the Spitfire SIP Peer created earlierChange the Route Type to “PSTN Access Via DPNSS”From here the ARS can be configured as per normal to point outbound external calls to the Spitfire ARS Route.9
