# QoS and DSCP tag protocols

> **Applies to:** Tmedia 2.9 and higher

Starting with version 2.9, each IP protocol used on the units can support DSCP tagging (adding a Type of Service or [TOS](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/parameters/packet-network-type-of-service/README.md)).

This allows for Quality of Service (QoS) configuration on a network.

Here is the list of protocols and how to configure them:

* SIP: [Creating a SIP Transport Server](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/creating-a-sip-transport-server/README.md)
* Sigtran IUA: [Creating IUA Peers](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/creating-iua-peers/README.md) (in advanced parameters)
* Sigtran M2PA: [Adding M2PA Links](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/adding-m2pa-links/README.md)
* Sigtran M2UA: [Creating M2UA SAP](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/creating-an-m2ua-sap/README.md)
* Sigtran M3UA: [Creating M3UA SAP](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/creating-an-m3ua-sap/README.md)
* SNMP: [Configuring SNMP](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/configuring-the-snmp-agent/README.md)
* Radius: [Adding RADIUS Server](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/toolpack-adding-radius-server-s/README.md)
* HTTP: [Create HTTP Service](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/create-http-service/README.md)
* SSH: [Configure SSH Service](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/configuring-the-ssh/README.md)
* ICMP (Ping and others) : [Configure ICMP Service](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/configuring-the-icmp/README.md)
* DNS: [Configure DNS Service](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/configuring-the-dns/README.md)
* RTP: [RTP Audio Profile](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/voice-media/modifying-rtp-and-audio-settings/README.md)

## 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/ss7-and-signalling/qos-and-dscp-tag-protocols.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.
