What are the ports to open on my router and how do I prioritise flow?

In order to optimise the quality of your calls we recommend prioritising flow on your routers.
Here are the different elements constituting Ringover's infrastructure:
● SIP Proxy
SIP Proxy servers are used for the authentication and routing of SIP packets.

● Media
Media servers are used for implementing IVRs, transcoding audio streams, conference calls.

TURN servers offer an advantageous alternative: coupled with media servers, they allow tcp tunnelling on a port before rerouting to the media server.

With Ringover having at its disposal a fleet of flexible media servers, TURN technology makes it possible to establish fewer security rules. However, the client must support the turn. A failover is possible if the TURN servers cannot be reached.

● API & Front
API servers are used for processing CDRs, contacts, group conversations, text messages, etc.

General Rules:

*The web browser can open a random port between 1024 - 65535. We have no influence over this selection.

The ports to use on the server side are:
● HTTPS / TLS → port 443 (TCP)
● TURN → port 80 et 443 (TCP et UDP)
● RTP → port 20000-22000 (UDP)
● SIP → port 5060 (UDP et TCP) ou 443

Here are Ringover's IP blocks:

Finally, Google's STUN servers can be used for NAT detection:
