# 🌐 Kiwi VoIP – Using VoIP Phones with Mesh Networks & Starlink
As homes and offices become more connected, **Wi-Fi Mesh networks** are increasingly common — especially in properties with multiple levels or wide coverage areas. However, if you're running **VoIP phones or PBX systems over a mesh network**, particularly with **Starlink**, you may encounter issues that affect call quality.
This guide explains **common problems**, why they happen, and how to fix them.
---
#### 📶 Background: Mesh Networks & Starlink
Wi-Fi mesh systems are designed to extend wireless coverage seamlessly across a home or building. They work great for most devices — but when it comes to **real-time services like VoIP**, things can get tricky.
### Why?
When combined with **Starlink** or any **double NAT (CGNAT)** environment, your **IP phone might not communicate correctly** with the SIP server — leading to issues like:
- One-way or no audio
- Calls connecting then dropping
- Registration timeouts or failed provisioning
### What’s Happening?
Here’s a simplified explanation:
- The **mesh system assigns the IP address**, not the main Starlink router
- VoIP traffic is routed poorly or blocked altogether
- The SIP server struggles to “find” or return packets to the phone
---
#### 🔧 Common Fixes & Solutions
### ✅ 1. Enable Starlink Bypass Mode
- Use the **Starlink app** to enable “Bypass Mode”
- This turns off Starlink’s router function and allows your mesh to handle all routing/DHCP
- Restart your **IP phone**, **mesh**, and **router** after changes
> **Why this helps:** Ensures consistent routing for SIP packets and avoids double NAT issues
---
### ✅ 2. Use a Network Switch for Direct Connections
- Plug a **network switch** directly into your Starlink Ethernet Adapter
- Connect your **VoIP phone to one port**, and your **Wi-Fi Mesh to another**
- Disable DHCP on the mesh if possible (so the phone gets IP from Starlink router)
> **Check this:** If your IP phone shows an address like `192.168.x.x`, it’s likely being served by the correct DHCP source.
---
### ✅ 3. Disable SIP ALG
- Log into your mesh system or router
- **Disable SIP ALG** (Application Layer Gateway)
- This setting interferes with SIP traffic and should always be turned off
---
### ✅ 4. Change Transport from UDP to TLS
- Go into your IP phone or PBX settings
- Switch SIP transport protocol from:
- **UDP Port 5060 → TLS Port 5061**
- In many tests, TLS performs better on Starlink connections
---
#### 🧠 Summary
| Issue | Cause | Fix |
| --- | --- | --- |
| One-way/no audio | Mesh handling NAT poorly | Enable Bypass Mode or use a direct switch |
| Calls drop after a few seconds | SIP packets not routed | Use TLS or disable SIP ALG |
| Phones not registering | Incorrect DHCP source | Ensure correct network role/DHCP provider |
