# Register a Softphone (SIP phone)

This document provides a step-by-step guide on how to register using `Zoiper` and`Bria Solo`. It includes screenshots for each step, highlighting important configurations such as SIP Transport settings.

To register to your [Connection](/components/connection.md) on [VoIP Number](https://app.voipnumber.net/dashboard) you need your Connection `SIP user` and `SIP password`. The SIP domain name is always the same: `sip.voipnumber.net` .

### **Verify DTMF Mode (RFC 2833) and SIP Transport Settings (TCP or UDP)**

* Go to "Settings" > "Accounts" > Your SIP Account > Click Advanced >Scroll down to "Compatibility modes and Network Related".
* Ensure "DTMF Mode" is set to `RFC 2833` and that "SIP Transport" is set to **TCP** (you can also use `UDP` but it may require extra configuration on your firewall/router).

✅ All done!

### Troubleshooting

If you are behind a non standard NAT and you have troubles connecting, experiment with `STUN` and `rport` settings. It should be disabled by default and it should also be disabled if you use VPN, but you may find it working in particular scenarios.

### Select codecs

* Go to "Settings" > "Accounts" > Your SIP Account > Click Advanced >Scroll down to "Audio codecs".
* Make sure `OPUS/48000` , `G722` , `G.711 mu-law` (PCMU) and `G.711 a-law` (PCMA) are on `Selected codecs` the list. If they are not, then find them on `Available codecs` list and move them to the right column by pressing '->' (appears when you move the mouse over a selected codec). If you have multiple codecs on a list sort it so that the best-quality codecs are at the top and the lower-quality codecs are at the bottom.
