How to configure my router ports and prioritize traffic

Configuring your router allows you to optimize your call quality and ensure smooth Voice over IP communication. In this guide, you'll learn how to identify which network ports to open, allow IP address blocks, and prioritize your data flows. 

In order to optimize your call quality, we recommend setting up Quality of Service (QoS) flow prioritization on your routers. To do this, follow these configuration steps.

1. Understanding the Ringover infrastructure 

To accurately target which flows to allow and prioritize, it is essential to identify the various components that make up the Ringover infrastructure:

• SIP Proxy: These servers manage authentication and routing for your SIP packets.
• Media: These servers run PBXs, perform audio stream transcoding, and host conference rooms.
• TURN: Paired with media servers, they perform TCP tunneling on a specific port before redirecting traffic to the media servers.
• API & Front: These servers handle all processing related to CDRs (call logs), contacts, collaborative conversations, and SMS.

2. Configuring port forwarding on your router 

To enable proper communication between your equipment (or applications) and the Ringover infrastructure, you must configure communication ports.

Configuration steps 

1. Log into the admin interface of your network router.
2. Navigate to the firewall management tab or security access rules.
3. Create outbound traffic rules to allow the following ports:

Ports to allow on the Client side (You)

• Ringover / Desktop App / Chrome Extension (Ringover Dialer):
  • 1024–65535 / UDP (with outbound flow asterisk)
  • 1024–65535 / TCP

Ports to allow on the Server side (Ringover)

• HTTPS / TLS: Port 443 / TCP (also used for SIP)
• SIP: Port 5060 / UDP and 5060 / TCP
• TURN: Port 80 and 443 (in TCP and UDP)
• RTP (Audio Flow): Ports 20000–22000 / UDP
• Standard traffic (Front/API): Port 80 / TCP and 80 / UDP

3. Allowing Ringover IP address blocks 

To secure access while allowing legitimate communications through, add the following IP address blocks to your router or firewall whitelist:

Europe IP Blocks

• Standard IP (V4):
  • 185.63.92.0/22
  • 154.44.180.0/24
  • 45.151.184.0/22
  • 62.4.10.0/24
• Standard IP (V6):
  • 2a03:ba0::/29
  • 2a0f:3500::/29
• Load Balancer IP / Europe WEB:
  • 185.16.110.0/24
  • 51.159.75.59 | 51.159.24.24 | 51.159.26.141 | 195.154.68.85
  • 51.159.74.199 | 51.159.24.36 | 195.154.70.68

International IP Blocks

• Miami: 89.187.173.130 to 89.187.173.134 | 212.102.61.0/27
• New York: 138.199.41.192/27 | 185.63.16.0/22
• Dallas: 212.102.40.200 | 212.102.40.201 | 212.102.40.202
• Chicago: 143.244.61.96/27
• Atlanta: 138.199.2.96/27
• San Jose: 169.150.221.0/27
• Bogota: 169.150.228.193 | 169.150.228.194
• Mexico (Queretaro): 121.127.43.17 | 121.127.43.18
• Singapore: 143.244.33.113 | 143.244.33.114 | 143.244.33.115
• Sydney: 143.244.63.109 to 143.244.63.113 | 143.244.63.121
• London: 169.150.213.0/27
• Madrid: 37.19.215.0/27
• Johannesburg: 169.150.238.49 | 169.150.238.50
• Reunion Island: 80.69.217.96 | 80.69.271.97

4. Enabling flow prioritization (QoS) 

To ensure no other traffic on your local network affects voice quality, you must configure bandwidth prioritization.

Configuration steps

1. Access your router's QoS (Quality of Service) or Traffic Prioritization settings.
2. Create a new high/maximum priority rule for voice traffic.
3. Prioritize RTP media traffic by configuring destination ports 20000–22000 / UDP.
4. Prioritize SIP signaling traffic (ports 5060 / UDP and TCP) as well as the TURN protocol (ports 80 and 443 in UDP and TCP).
5. If necessary, add Google STUN NAT detection servers as prioritized or allowed:
   • stun.l.google.com:19302
   • stun1.l.google.com:19302
   • stun2.l.google.com:19302

🎉 You now know how to open your router ports and prioritize your traffic, allowing you to enjoy optimal call quality with Ringover!
