Configuring the Trunk with 3CX
The general instructions outlining how to add a new SIP Trunk to your 3CX installation can be found here.
Adding the Trunk
Go to “SIP Trunks” and select “Add SIP Trunk”
- Select Country: CA
- Select Provider in your Country: IXICA
- Main trunk number: One of the DID numbers you have been assigned. You must enter the number in the 11-digit number format (e.g. 18135910130)
- Press “OK”
Under the “General” tab in the “Trunk Details” enter the registrar, and in the “Authentication” section your Authentication ID and Password (these will be supplied to you by IXICA).
Once you have filled in these fields as given to you by IXICA, scroll to the top of the page and press OK. At this point if you refresh the page you should see your IXICA Trunk appear as “Registered”.
Adding Additional DIDs
To associate all other DIDs/Numbers you have in your IXICA account with 3CX, go to the Management Console → SIP Trunks, double-click on your IXICA Trunk and go to the “DIDs” tab.
Here you should already see 1 entry that is the Main Trunk number you have set. Add all other DIDs/Numbers you have to the list in a 11-digit number format (e.g. 18135910130) and press OK once you have finished.
Creating Inbound Rules
Now that you have associated all your DIDs/Numbers with your SIP Trunk in 3CX, you can create Inbound Rules to set where calls will be routed when those numbers are called. Instructions on how to create Inbound Rules can be found here.
When configuring IXICA SIP Trunks in 3CX, all numbers should be entered in a 11-digit number format (e.g. 18135910130), otherwise call routing may fail.
Outbound Caller ID
IXICA SIP Trunks support Clip No Screening which means you can present any number you want when calling outbound.
To do this you will need to format the DDI in a 11-digit number format (e.g. 18135910130) under the “Outbound Caller ID” of the individual extension.
When using IXICA to make outbound call, the dialed number can be in either a 11-digit or 10-digit number format.
More information about how to create Outbound Rules and how they work can be found here.
