Mitel 3300ICP = 192.168.1.2
Number range = 5xx
Trixbox = 192.168.1.101
Number range = 25xx

On the Mitel 3300ICP - 

1. Network Element Assignment
- create a network element for the local switch
- create a network element for each SIP peer, gateway, or Service Provider
- create a network element for the Outbound Proxy if one exists in your network 
Ensure there is a local element for the Mitel. if there is none, create it.

Create a network element for the Asterisk box
Name - Asterisk
Type = Other
FQDN or IP adress = 192.168.1.101 (Asterisk IP Address)
SIP Peer = selected
external FQDN or IP = 192.168.1.101 (Asterisk IP Address)
SIP registrar FQDN or IP = 192.168.1.101 (Asterisk IP Address)
Transport = UDP and Port = 5060 for all

2. System IP Port Assignment
Change the SIP UDP, TCP, or TLS port number if it is different from the default
value.
SIP UDP = 5060
SIP TCP = 5060
SIP TLS = 5061

3. DID Ranges for CPN Substitution
To set up the CPN Substitution table for outbound calls, enter a DID number or a
range of DID numbers assigned in the system.
Then enter the corresponding CPN substitution number that will be delivered for
that range e.g
Index = 10
DID Range = 500-599
CPN Substitution = 5XX

4. Create a SIP Peer for Asterisk
- Use SIP Peer Profile Form
SIP peer profile label = Asterisk
Local Account registration username = 150 (an extension that would be used for
authentication, should match in Asterisk)
Adress type = IP adress : 192.168.1.2 (ip address of 3300 ICP)
Authentication username = 150 (an extension that would be used for
authentication, should match in Asterisk)
password en confirm password = abcd (password set on extension, should match in
Asterisk)
Authentication = Challenge-based Authentication
Outgoing DID Ranges: select index 10 (select matching index if Calling Party
Number Substitution was configured)

5. Optional - SIP Peer Profile Assignment for Incoming DID
To associate a range of telephone numbers assigned by a SIP Service Provider to
a particular SIP Peer,
enter the required information in this form.

6. Trunk Service Assignment:
Configure the trunk as non-dial in or dial-in:
- update the Non-Dial-In Trunks Answer Point field for the incoming calls.
- strip the number of leading digits in Dial-In Trunks Incoming Digit
Modification Absorb field
- add the appropriate number of digits in Dial-In Trunks Incoming Digit
Modification Insert field.

Trunk service number = 10 (based on my situation)
class of service = 64 (Enter the COS number that defines the required options
for the trunk)
class of restriction = 64 (Enter the COR number for the trunk. This COR number
must not have been assigned to a station (mandatory field))
trunk label = Asterisk trunk
Dial in Trunks Incoming Digit absorb = 0 (you can use this to do leading digits
absorption etc)

7. Class of Service Options Assignment
Enable the Public Network Access via DPNSS field in the class of service for all
devices that make outgoing calls through
SIP trunks, PRI trunks, LS trunks, and so forth that are connected to SIP
Trunks.

8. Route Assignment
Complete the following fields in this form:
- select SIP Trunk from the pull-down list in Routing Medium.
- select a SIP Peer Profile label from the SIP Peer Profile pull-down list.
- enter a Class of Restriction group number in COR Group Number (this determines
which extensions *cannot* access this trunk, I am using a COR that
permits all Mitel extensions to access the Sip trunk and therefore call Asterisk
users successfully)
- enter any required digits in Digits Before Outpulsing. (If this field is left
blank, digits will be sent out as "Enbloc".)

Route number = 10
Routing medium = SIP Trunk
Trunk group number = empty
SIP Peer profile = Asterisk
Route Type = PSTN access via DPNSS

- ARS Digits dialed Assignment:
Digits Dialed = 2 (2 is the first digit of my Asterisk extensions
Numbers to follow = 3 (5xx follow = 3 digits)
Termination Type = route
Termination number = 10 (route number created above)

Make sure to enable Public Network Access via DPNSS in the SIP trunk COS.

On the Trixbox - 

- Create a SIP trunk:
Outgoing Trunk name = Mitel
PEER Details:
allow=ulaw
auth=md5
context=from-pstn
host=192.168.1.2
insecure=very
nat=no
secret=abcd
type=peer
username=150

- Create a SIP Extension:
Display name = Mitel 3300ICP
Device options:
secret = abcd
canreinvite = no
context = from-internal
host = dynamic
type = peer
nat = no
port = 5060
dial = SIP/150

- Create an outbound route:
Route name = Mitel3300ICP
Dial patterns = 5XX
Trunk Sequence = 0 SIP/Mitel

- Create inbound routes for your SIP extensions:
for example SIP extention 2540:
- DID number = 2540
Set destination = core: extension 2540

Now you should be able to make call from SIP to Mitel and vice versa.
