Configuring Elastix 2.0.0 57 for
Spitfire SIP Trunks
This document is a guideline for configuring Spitfire SIP trunks onto Elastix 2.0.0 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.

Outbound Routing – Reference only: Page 9
Inbound Routing: Page 10
Outgoing CLI: Page 11
Add SIP Trunk
Paste the following into the appropriate file (I have used extensions_custom.conf) as highlighted below. This will allow the elastix to read & route incoming DDI calls. Please note that the goto step may need to be changed to suit your programming. Although this code was tested as working in this installation it comes with no warranty from Spitfire. [ParseDDI_from_ToHeader] exten => _.,1,Set(parseDDI=${SIP_HEADER(To)}) exten => _.,n,Set(parseDDI=${CUT(CUT(parseDDI,@,1),:,2)}) exten => _.,n,Goto(from-trunk,${parseDDI},1) Select “Save”.
Add SIP Trunk continued Select “sip_nat.conf
Paste the following into sip_nat.conf . This will change the default expiry timer on the SIP trunk to 10 minutes maxexpiry=3600
Add SIP Trunk continued General Settings
1. Trunk Description: A logical name for the trunk
2. Outbound Caller ID: Enter the User name as supplied by Spitfire without the leading 44.
Please note that this is just the number and DOES NOT include @spitfiretsp.net. This is the number that will be presented if there is no individual CLI presentation per extension
3. CID Options: Determined by the installer 4. Maximum Channels: As specified by Spitfire
4. Disable Trunk: Determined by the installer. I would suggest No 5. Monitor Trunk Failures:Determined by the installer
Outgoing Dial Rules (Reference Only)
1. Dial Rules: Determined by the installer
2. Dial Rules Wizards: Determined by the installer, but normally blank on Spitfire trunks
Outgoing Settings
1. Trunk Name: Give the trunk a logical name
2. PEER Details: Enter the details below in the PEER Details area.
Please Note: Not all the details required are shown in the screenshot – they are listed below with a brief description. There are also other settings available for use in the PEER Details, but the ones below are those required to work with Spitfires SIP trunks. Other settings may have a negative impact on the SIP trunks, but this will need to be determined by the system installer.
type=peer
host=83.218.143.16 (or spitfiretsp.net) outboundproxy=mproxy3.spitfiretsp.net
username=your username as supplied by Spitfire (i.e. 442031410025)
secret=password as supplied by Spitfire
fromuser= your username as supplied by Spitfire (i.e. 442031410025)
fromdomain=spitfiretsp.net sendrpid=yes
insecure=invite disallow=all allow=alaw
qualify=no (or yes if required for fallback) canreinvite=no
progressinband=yes this setting may be required if you are using call forward/divert to an off-switch destination. Without this setting, the call will establish but you may not hear any speech.
Add SIP Trunk continued Incoming Settings
1. User Context: Leave blank 2. User Details: Leave blank Registration
1. Register String: Enter the Register string in the following format:
Format: Username:[email protected]/DDI Number or
Username:[email protected]/DDI Number
Example as below: 442031410025:[email protected]/442031410025 Select “Submit Changes” when finished
Note: In this example I am simply modifying an existing “Dial 9” route to use our newly created trunks. The installer may add or amend routes as necessary.
Select “Outbound Routes”, then “0 9_outside”
Inbound Routing – Reference only
Please Note: There are many fields available in the Inbound Routes field. This guide is only intended to
demonstrate an incoming DDI call only. The installer will determine if any of the other fields are required for each DDI programmed.
Select “Inbound Routes” on the “PBX Configuration” panel on the left of the screen. Add or edit an Incoming Route
1. Description: Give the incoming route a logical name.
This reference shows how to modify the outbound Caller ID on a single extension. This will over-ride the
“Outbound Caller ID” in the SIP trunk (Page 6). The number must be a valid DDI associated with the Spitfire SIP trunk WITHOUT the leading 44.
In PBX Configuration, Extensions select the extension you wish to modify. Go to “Outbound CID” under “Extension Options”
1. Enter the CLI number in the format below (i.e. drop the leading 44 from the DDI number) and “Submit”
