In order to use Vitelity SIP trunks with 3CX, some configuration must be made within the provider's portal and some information is required to complete the configuration with 3CX.
The portal can be accessed here with the credentials given to you by Vitelity.
The first thing you should do after logging into your portal is purchase the Numbers/DIDs you want to use.
To do this go to the “Buy Now” section on the left and from the “Phone Numbers” menu, proceed with purchasing the DIDs/Numbers you want.
Adding IP Endpoints
Although Vitelity supports both registration-based (requires username and password) and IP-based (requires static Public IP) Trunks, the 3CX template is made for IP-based Trunks, so the internet connection your 3CX server uses must have a static Public IP.
This means that the next step is to insert your 3CX Public Static IP into the Vitelity Portal. To do that, from the menu on the left, under category “My Products & Services” select “Sub Accounts”. Here scroll to section “IP Address Endpoints” and add your Static Public IP to the list of IP Endpoints. This will enable Vitelity to know where to send incoming calls to and also secure your account from being used by other unauthorized parties.
Once you have added the IP Address, press on “Select Action” next to it in the list and select “Note”.
This will redirect you to add a Note to this IP. Here enter a friendly name for the IP Address as it will be used later on.
Assigning Numbers to the IP Endpoint
Now it is time to assign the DIDs/Numbers you have ordered to the IP Endpoint you created in the previous section.
To do this, in the “Account Management” category, go to “Settings” and then select “Routing”. Here, in the “Default Destination” section, select the IP of the Endpoint you want incoming calls to be routed to, then press “Update”.
From this point onward, all incoming calls to any already purchased numbers or numbers you may purchase through your account in the future will be routed to the Endpoint you have specified here.
Collecting 3CX Configuration Settings
As Vitelity will be an IP-based Trunk in 3CX, the only information required is the IP of the Vitelity Server that you should be connecting to.
For this, from the Vitelity Portal open a ticket with Vitelity and request they provide you with the Server IP that you should configure 3CX to connect to.
Once Vitelity replies back, make note of the IP you have been given as you will need it to configure the Trunk in 3CX.
Configuring the Trunk with 3CX
The general instructions outlining how to add a new SIP Trunk to your 3CX installation can be found here.
Specifically what you will be needing is:
- The IP Address given to you by Vitelity (see section “Collecting 3CX Configuration Settings”)
- The DIDs/Numbers you have assigned to your IP Endpoint (see section “Collecting 3CX Configuration Settings”)
Adding the Trunk
In the Management Console go to the SIP Trunks node and press “Add SIP Trunk”. Select Vitelity and in the “Main Trunk No” field enter one of the DIDs/Numbers you have in a 10-digit format, then press OK.
Once you have done this and you have been brought to the SIP Trunk settings, enter the Vitelity Server IP Address given to you by Vitelity in the “Registrar/Server/Gateway Hostname or IP” field, then press OK.
Adding Additional DIDs
To associate all other DIDs/Numbers you have in your Vitelity account with 3CX, go to the Management Console → SIP Trunks, double-click on your Vitelity 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/Number you have to the list in a 10-digit format and press OK once you have finished.
Creating Inbound Rules
Now that you have associated all your DIDs/Number 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 Vitelity SIP Trunks in 3CX, all numbers should be entered in a 10-digit format otherwise calls will be rejected.
Outbound Caller ID
Vitelity SIP Trunks support Clip No Screening which means you can present any number you want when calling outbound.
There are no special instructions regarding Outbound Rules that are required, numbers can be dialed either in 10-digit format, 11-digit format or full + e164 format (e.g. +18135791691).
More information about how to create Outbound Rules and how they work can be found here.
