Configuring the Trunk with 3CX
SIPbase-reventix Portal Configuration
Before configuring your SIPbase-reventix SIP Trunk in the 3CX Management Console, there are some settings you need to make in the providers portal. Login with the credentials you have been given and go to “VoIP” → “Accounts”.
At the bottom of the page you will see all the SIP Trunk accounts SIPbase-reventix has assigned to your account:
Here make note of the “Account Number” as this will be used in the next section to register your SIP Trunk in 3CX and will be used as your “Authentication ID”.
Next, press the “Edit” button to the right of the account you want to register with 3CX.
This will take you to the Account Configuration where in section “Phone Number”, you must set field “SIP-header for phone number transmission” to value “Remote-Party-ID ( for 3CX )”.
Important: Not setting this value may result in some inbound calls to your system to not be routed correctly!
While still in the Account Configuration, make note of the password of this account which you can find in the “Password” section:
Once you have made all the changes and collected all the information you need, press “Save” at the bottom of the page.
Adding the Trunk
Before reading this section, make sure you have followed the instructions and gathered in the information outlined in the previous section “SIPbase-reventix Portal Configuration”.
The general instructions outlining how to add a new SIP Trunk to your 3CX installation can be found here.
Go to “SIP Trunks” and select “Add SIP Trunk”
- Select Country: DE
- Select Provider in your Country: SIPbase-reventix
- Main trunk number: This will have been provided to you by SIPbase-reventix. You must enter the number in the International number format (e.g. 00495114740240)
- Press OK
Under the “General” tab, in the “Authentication” section enter your SIP Username and Password as you found them in the SIPbase-reventix Portal, explained in the previous section.
Once you have filled in these fields as given to you by SIPbase-reventix, scroll to the top of the page and press OK. If you refresh the page you should see your SIPbase-reventix Trunk appear as Registered.
Adding Additional DIDs
To associate all other DIDs/Numbers you have in your SIPbase-reventix account with 3CX, go to the Management Console → SIP Trunks, double-click on your SIPbase-reventix 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 International dialing format (e.g. 00495114740240) 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 SIPbase-reventix SIP Trunks in 3CX, all numbers should be entered in the International dialing format (e.g. 00495114740240), otherwise call routing may fail.
Outbound Caller ID
SIPbase-reventix Trunks support Clip No Screening as a separate paid service. This means that without this extra service enabled, when making outbound calls you can only present numbers you have associated with your account as Outbound Caller ID.
To enable Clip No Screening, you must come in contact with your SIPbase-reventix representative to have it enabled for you.
Once this service is enabled, you can present any number as outbound caller ID, not only numbers you have associated with your account.
When configuring any field in 3CX that affects the Outbound Caller ID, the number you want to present as CLI must be entered in the E.164 dialing format (e.g. +495114740240).
When configuring your Outbound Rules make sure that all numbers are dialed either in the National (e.g. 05114740240) or International (e.g. 00495114740240) format.
