# How to debug VoIP

The VoIP ports can be used for SIP, RTP and Sigtran (M2PA, M2UA or M3UA). Here are different way sto debug:

* Setting the VoIP address. Follow the Web portal [Configuring Ip Interfaces](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/sip-voip/configuring-ip-interfaces/README.md).
* Verifying the IP address configured

From the web portal:

```
Status -> Adapters -> voip0 (or any other interface)
```

From the command lines: Access to the Tmedia unit using SSH. Access the telecom baseboard of the Tmedia using telnet

```
telnet 172.31.1.1
```

```
ifconfig -a
```

* Pinging a remote device from the VoIP ports

 Access to the Tmedia unit using SSH.  Access the telecom baseboard of the Tmedia using telnet

```
telnet 172.31.1.1
```

Ping the remote unit by specifying the local VoIP port to use. For example, if the IP address of the local VoIP port is 68.67.49.147 and the remote is 208.94.105.1 :

```
ping -B 68.67.49.147 208.94.105.1
```

## 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/telecom-references/sip-and-voip/how-to-debug-voip.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.
