SprintHub offers an essential tool for testing the integration of external platforms via SIP with our VoIP framework. This process ensures that your operation will function in a stable and efficient way within SprintHub.

But beware: there are **two test links** different, each with a specific purpose. Below we explain when and how to use them, as well as why the test is so important.

***

#### 🧪 1. Link for Those Who Are NOT Yet Clients

If you still **are not a SprintHub client**, use the following link:

🔗 <https://master.sprinthub.app/voip/tester>

This link is ideal for integrators or interested parties who want to validate in advance the compatibility of their telephony platform with SprintHub before contracting or migrating.

***

#### ✅ 2. Link for Those Who Are Already Clients

If you already have an active instance with SprintHub, access the test using the following format:

🔗 `https://nomedainstancia.sprinthub.app/voip/tester`

> Replace `nomedainstancia` with your instance name.\
> Example: `https://minhaempresa.sprinthub.app/voip/tester`

> **Requirement:** It is necessary to be **logged out** of the SprintHub platform for access to work properly.

***

#### 🎯 Why perform the test?

The purpose of the test is **to verify whether your external telephony platform is accepted by SprintHub via external SIP**.

For the integration to work, the external platform must necessarily support **WebSocket connection (WSS)**. This protocol is what enables real-time communication between SprintHub and your VoIP provider.

**❗ If the test is unsuccessful:**

It is still possible to use SprintHub normally, as long as the number is **ported to Vox Implant** (our approved provider).\
In this scenario, the Vox Implant technical team needs to assess the possibility of portability and the technical feasibility.
