# Creating a SIP Stack

> **Applies to:** Tmedia 3.0, 3.2, 3.3

Session Initiation Protocol, more commonly known as [SIP](https://telcobridges.com/learning/sip-trunking/what-is-sip/), is a signaling protocol for packet-based networks and is commonly used, along with H.323 to provide signaling for Voice over IP (VoIP) communications. You must configure SIP signaling for your system. The first step in doing so is to create a SIP stack:

1- Click **SIP** in the navigation panel

![SipNav C 0](https://docs.telcobridges.com/w/images/a/a9/SipNav_C_0.png)

2- Click **Create New Sip**

![Sip C 1](https://docs.telcobridges.com/w/images/7/78/Sip_C_1.png)

3- Create the new SIP stack:

* Verify that the box labeled **Enabled** is checked
* Enter a **name** for the stack
* Click **Create**

![Sip B 2](https://docs.telcobridges.com/w/images/2/25/Sip_B_2.png)

4- Verify that the **"SipCfg was successfully created"** message appears

![Sip B 3](https://docs.telcobridges.com/w/images/a/ad/Sip_B_3.png)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://prosbcdocs.telcobridges.com/tmedia-documentation/configuration/creating-a-sip-stack.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
