Configuring Twilio Interconnect Trunk

Before proceeding with the next steps, you need to .

Twilio Interconnect Trunk

Twilio Interconnect is an alternative to the open Internet that provides private connections between your network and Twilio. It offers the best performance and data throughput and the lowest latency. Since your data never touches the public Internet, it also provides the best security and can guarantee quality from end to end.

For more details please check:

Choose the product that is right for you

There are several reasons why Interconnect is the preferred method of connecting to Twilio. High availability, guaranteed data throughput_, quality of service, and enterprise-grade security are just a few of the strong arguments for making use of Twilio Interconnect. If you need highly consistent connectivity between your communication infrastructure and Twilio, then Twilio Interconnect is the right choice likewise, if you have policies (internal or external) that preclude you from sending traffic across the open Internet — for example, HIPAA, PCI, or GDPR.

Twilio Interconnect has several flavors to accommodate various use cases:

  • allows you to set up a dedicated, physical fiber interconnection with Twilio.

  • is a way of having a private connection through a third-party provider that Twilio has an exchange agreement with.

  • is the best option if you want to quickly try something out and play with some ideas, or if you have no presence in any of our or our partners' data centers and wish to have a secure connection to us.

Create a SIP Trunk on the Twilio Platform

To create a new SIP trunk on the Twilio platform:

  1. Select the menu Manage > Trunks.

  1. Click Create new SIP Trunk, give it a friendly name, then press Create.

Trunk Termination

Once created, we can leave all of the settings on the General page untouched and switch over to the Termination section. When PortSIP PBX places a call, this is where it’ll be sending the call information to Twilio.

  1. Go ahead and configure a unique URI:

    • In the Termination section, enter a Termination SIP URI you prefer.

    • If there display the Available in green means that URI is acceptable. Click on Show localized URIs and copy the URIs information so you can use them to configure the trunk in your PortSIP PBX.

  1. Move down to the Authentication section. Starting with an IP ACL, create one that has the public IP address of your PortSIP PBX installation. This information is present in the PortSIP PBX Home page.

3. Create a username and password pairing in the Credential List. This info will also make its way into the PortSIP PBX Trunk configuration.

Press the Create button and now switch to the Origination page.

Configuring the Trunk with PortSIP PBX

The Twilio Interconnect trunk refers to the Register Based Trunk in PortSIP PBX.

You can configure the Twilio Interconnect Trunk at either the PortSIP PBX system administrator level or the Tenant Admin level:

  • If configured at the system administrator level, you can share this trunk with tenants.

  • If configured at the tenant admin level, this trunk can only be used by the tenant itself.

Please follow the below steps:

  1. Sign in to the PortSIP PBX Web Portal as a System Administrator or Tenant Admin. Navigate to the left menu and select Call Manager > Trunks.

  2. Click the Add button to open a menu. From the menu, choose Register Based Trunk.

  1. Enter the trunk name and choose the brand:

    • Name: Enter a friendly name for the trunk.

    • Brand: Select Twilio Interconnect from the Brand field. Important!

    • DID Pool: This step is only for you at the Tenant admin Level to configure this Register Based Trunk, you will need to set up your Twilio DID numbers for this DID pool for this trunk.

      • This tenant can only use the DID numbers within the DID pool range to create inbound and outbound rules and configure the outbound caller ID for extensions.

      • The DID pool can consist of a single number, a range of numbers, or a combination of both. For example:

        • 12027594810

        • 12027594810;12027594815

        • 12027594810-12027594815;12027594820

        • 12027594810-12027594815;12027594830-12027594845

  2. Hostname or IP Address: For this field, input one of your Twilio trunk Termination URIs that we saved in the above based on your PortSIP PBX location:

    • portsip-pbx.pstn.ashburn.twilio.com

    • portsip-pbx.pstn.umatilla.twilio.com

    • portsip-pbx.pstn.dublin.twilio.com

    • portsip-pbx.pstn.frankfurt.twilio.com

    • portsip-pbx.pstn.sao-paulo.twilio.com

    • portsip-pbx.pstn.singapore.twilio.com

    • portsip-pbx.pstn.tokyo.twilio.com

    • portsip-pbx.pstn.sydney.twilio.com

  1. Click the Next button, and enter the ID and Password that we had defined in the Twilio Credential List for the SIP trunk authentication name and password fields.

  1. Click the Next button, you can adjust the options for the trunk.

    • You must turn off the Need Registration option since the Twilio Interconnect trunk doesn't accept the REGISTER message.

    • Max Concurrent Calls: This field sets the maximum number of calls that PortSIP can establish with this trunk. You can adjust it to an appropriate value.

    • We recommend keeping the default settings for other options unless you have specific requirements.

  1. This step is only available when configuring the Register-Based Trunk at the System Administrator Level. Click the Next button to assign this trunk to the tenants and provide your Twilio DIDs/Numbers to them with the DID Pool (DID numbers). A DID can be only assigned to one tenant.

    • A tenant assigned to this trunk can only use the DID numbers within the DID pool range to create inbound and outbound rules and configure the outbound caller ID for extensions.

    • DID Pool: The DID pool can consist of a single number, a range of numbers, or a combination of both. For example:

      • 12027594810

      • 12027594810;12027594815

      • 12027594810-12027594815;12027594820

      • 12027594810-12027594815;12027594830-12027594845

Click the OK button to save the changes, the trunk configuration is completed.

Since the Twilio trunk is turned off the Need Registration option, in the trunk list page you will always see the status displayed as Registered.

From your , navigate to the Elastic SIP Trunking area (or click on the icon on the left vertical navigation bar).

In the Origination section of the configuration, configure your origination SIP URI, which identifies the network element entry point into your PortSIP PBX. To ensure your calls go over your private connection include the edge parameter in the URI with the value of the Twilio where your private connection is configured, for example:
