Description

STUN keep-alive mechanism for SIP, which can be turned on manually by specifying the address of the STUN server followed by the port number. However, we strongly discourage you from using it, because it can not work properly in symmetrical NAT environments (i.e., linux-based router/firewall). The only general SIP NAT solution is a session border controller (SBC) on the service provider’s side.

For an alternative to STUN see unsaf_via_received_rport.
