In this post I’ll show how to create a Sip trunk between Avaya IP Office and Asterisk pbx.

Avaya IP Office Side
a) Enable SIP Trunks in System Configuration (System – LAN1 – VOIP)
b) Create a new SIP Trunk

-- SIP Line
ITSP Domain Name: <empty>
In Service: Y
Eveything Else: <default>

-- Transport
ITSP Proxy Address:
Layer 4 Protocol: UDP
Send Port: 5060
Use Network Topolgy Info: LAN1
Eveything Else: <default>

Att.: SIP Licenses are required for this step.

--SIP Credential
Add a new SIP Credential as below.
UserName: <SIP Extension's username on Asterisk for Avaya IpOffice>
Authentication Name: <SIP Extension's username on Asterisk for Avaya IpOffice>
Contact: <SIP Extension's username on Asterisk for Avaya IpOffice>
Password: <SIP Extension's password on Asterisk for Avaya IpOffice>
Expiry: 60
Registration Required: Y

-- SIP URI
Add a new channel as below.
Local URI: Use internal Data
Contact: Use internal Data
Display Name: Use internal Data
PAI: Use internal Data
Registration: <Index of set in SIP credential>
Incoming Group : <Make sure to set the groups to something unique.>
Outgoing Group : <same as Incoming group>

c) Under Each User, under there SIP Tabs make sure to set their Sip Name and extension number.

d) Create an Incoming Call Route

Bearer: Any Voice
Line Group : <Value from SIP URI>
Eveything Else: <default>

Destination Tab
Default Value is . (just a period)

e) Short code for calling the Asterisk Box. The extension on my asterisks are 8xx.
So my short code codec looks like the next.

Code: 8XX  ( Change this with your extension format )
Feature: Dial 3k1
Tel Number: 8N”@<Asterisk Ip Address>” (Replace with IP of asterisks)
Line Group : <Group Id Set in SIP URI Tab>

Asterisk side
a) Create a SIP Trunk that looks like this:

Trunk Name: <SIP Extension's username on Asterisk for Avaya IpOffice>
Peer Details:

type=friend
username=<SIP Extension's username on Asterisk for Avaya IpOffice>
fromuser=<SIP Extension's username on Asterisk for Avaya IpOffice>
secret=<SIP Extension's password on Asterisk for Avaya IpOffice>
context=from-trunk-sip
qualify=yes
insecure=very
canreinvite=no
host=dynamic
disallow=all
allow=alaw&ulaw

b) Create an Outbound Route

Route name: IPOffice
Intra Company Route <checked>
Dial Patterns : 6XX  <Replace with the format of your IP Office extension>

Trunk Sequence: <Select the trunk you created above>
