Do I Need to Configure My Home Firewall for VoIP?

Most home routers come with UPnP support, which automatically manages VoIP traffic.

If UPnP is disabled or unavailable:

1. Ensure outbound SIP (UDP 5060 / TCP 5060, TLS 5061/5065, WSS 8089), and 10000-20000 (RTP) are allowed.
2. If you are experiencing one-way audio, manually forward RTP port to your device.

NOTE

Security tip: When opening ports, make sure access is limited to your PBX IP address.
