STUN server
Requirements:
•
IP operating mode IPv4
•
NAT traversal Enabled with use of STUN
A STUN server provides information to subscribers on a private network on
request. This information includes the IP address and port outside their
private network that is viewed as the source of their data. This information
is entered in the requests, instead of the actual private IP address/port.
Notes:
If you encounter problems with unilateral call connections, enabling the
RTP port might help.
The Overviews > Ports page shows an overview of the PBX ports
(incoming and outgoing).
Caution: Every time port forwarding is performed, there is a
security risk.
