Configure a firewall to allow join.me VoIP

Trouble connecting to audio? You may need to check your firewall settings.

The join.me internet calling service uses the SIP standard to facilitate communication between the computer and the conference service. In some environments, this may require certain ports and IP ranges to be opened in your firewall.

The following port ranges should be allowed through your firewall:
  • 443, 5060-5100 TCP Outbound (SIP Signaling ports)
  • 7800-32000 UDP Outbound (Voice Traffic ports)
These ports should be opened to a specific IP address range:
  • 189.8.82.112/28
  • 117.120.4.96/28
  • 115.187.137.232/29
  • 185.167.188.0/22
