I figured I'd post this HowTo on how to setup a SIP trunk between a IP Office and a Asterisks Phone system for intra extension dialing because I just spent the last 3 days trying to figure this out, and there seams to be plenty of articles on how to do this via H323, but there are very limited docs/HowTo's on doing this via SIP.
At the end of the day, this was a lot simpler that I expected, but I learned alot in the process.
------------------------
Avaya IP Office Side:
------------------------
1) Create a new SIP Trunk ( SIP Licenses are required for This )
2) The only thing you fill in here is the IP address of Asterisks/TrixBox,FreePBX box. Please note that this is being done anonymously, so I assume the two machines are either on the same LAN or connected securly via a VPN> I would not recomened this setup if you are doing this over the internet.
ITSP Domain: <blank>
IPSP IP : Asterisks IP
Prim Auth / Pass: <blank>
Eveything Else: <blank>
Check in Service box
3) Set Up SI URI - ADD a channel and set this to <use user Data> - Make sure to set the channel to something unique. I used group 420 for incoming and outgoing.
4) Other Tabs can be left default settings
5) Create a short code for calling the Asterisk Box. The extension on my asterisks are 4xx. So my SC looks like this:
Code: 4XX ( Change this with your extension format )
Feature: Dial 3k1
Tel Number: 4N"@x.x.x.x" (Replace with IP of asterisks)
Line Group : 420 (Group Id Set in URI)
6) Create an Incoming Call Route Like this:
Bearer: Any Voice
Line Group : 420
<the rest you leave default>
Under Destination
Default Value is . (just a period)
7) Under Each User, make sure to set their Sip Name to their extension number under there SIP Tabs.
-------------------------------
ASTERISK SIDE via FreePBX GUI
-------------------------------
1) Create a SIP Trunk that looks like this:
Trunk Name: IPO
Peer Details:
host=x.x.x.x (IP of IP Office)
type=friend
2) Create an Outbound Route
Route name: IPOffice
Intra Company Route <checked>
Dial Patterns : 2XX ( Replace with the format of your IP Office extension )
Trunk Sequence: SIP\IPO
3) Under General Settings
Set "Allow Anonymous Inbound Sip Calls" to yes
That should be it, you should now be able to call back and forth between the 2 systems as if they are one.
