Built for FreePBX Environments

Everything Needed to Connect Your PBX to the Public Telephone Network.

Triton combines SIP connectivity, number services, routing visibility and practical technical support for businesses and service providers operating FreePBX.

PJSIP Trunking

Use modern PJSIP trunk configuration with settings matched to the authentication and routing model.

IP Authentication or Registration

Choose IP-based authentication for static environments or registration where that model better fits the deployment.

Inbound DID Routing

Map local and toll-free numbers to extensions, ring groups, IVRs, queues or other FreePBX destinations.

Outbound Route Support

Validate dial patterns, caller ID formatting and trunk selection before production launch.

Deployment Workflow

From Trunk Credentials to Completed Test Calls.

A structured setup process reduces guesswork and makes production cutovers easier to control.

01

Choose Authentication

Confirm whether the trunk will use source-IP authentication or SIP registration.

02

Configure PJSIP

Build the trunk with the correct server, transport, authentication and endpoint settings.

03

Create Routes

Configure inbound routes, outbound routes, caller ID and dial-pattern handling.

04

Test and Launch

Validate inbound, outbound, DTMF, audio, caller ID and failover before cutover.

FreePBX Configuration Areas

Focus on the Settings That Most Often Determine Success.

Many SIP problems come from a small set of configuration areas. Triton helps customers review the practical items that affect registration, routing and media.

Number and Calling Services

More Than Just a SIP Registration.

FreePBX deployments usually need number management, emergency services and operational visibility alongside the trunk itself.

Local & Toll-Free DIDs

Order new numbers or port eligible existing numbers into Triton.

E911

Associate eligible telephone numbers with emergency-service location information.

CNAM and Caller ID

Support caller-name workflows and validate outbound caller ID formatting.

CDRs and Usage

Review call activity and usage through Triton’s customer platform.

Number Porting

Coordinate documentation, FOC dates and production routing changes.

Alternate Routing

Design secondary destinations or Smart HA paths for eligible environments.

High Availability for FreePBX

Give Your PBX More Than One Way to Receive Calls.

Eligible FreePBX deployments can use alternate customer destinations and Triton’s two-region or three-region Smart HA routing to reduce dependence on a single path.
