What ports will I possibly need to open in my firewall?
Last Updated 7 months ago
There is generally no need for you to configure port forwards or
firewall rules. However, in cases where a firewall denies outbound
traffic by default or uses manual NAT, it may be helpful to open the following ports.
| Protocol | Port/s | Use |
|---|---|---|
| TCP | 80, 443 | Web UI's and provisioning servers |
| TCP | 80, 442, 443 | Instant Fax server |
| UDP | 5060 | SIP signaling |
| TCP | 7000, 7001 | Fax ATA |
| TCP | 8001 | Web Sockets |
| TCP | 8000 | Text-to-Speech |
| UDP | 8889 | Web Meetings and Video Conferences |
| UDP | 17000-35999 | RTP |
| UDP | 8090, 20000 | NPAT (Network Performance Assessment Tool) |
| TCP | 80, 443 | NPAT (Network Performance Assessment Tool |
The following ports are used by the UC Client
The UC Client only requires ports TCP/443 and TCP/9002 outbound. These carry encrypted web socket traffic. Port 9002 socket carries all SIP traffic. Additionally, audio communications are over DTLS (TLS for UDP) on ports 30000 - 40000 UDP.
The following ports are used by ReachUC:
- TCP - 443, 4998, 5060, 7080, 24998
- UDP - 4998, 10000-65535(for RTP/RTCP packets)
