field if
gateway is installed in a private network separated from the
2N BRI
®
Internet via NAT or firewall. The pre–set port for sending requests to STUN is
3478.

gateway public IP address. Use this parameter to configure the frequency of

Note
In case the GSM gateway is installed behind the NAT, make proper
routing settings in the NAT router for the relevant ports (SIP, RTP,
STUN). Integrated firewalls can also affect VoIP calls!
Tip
Should you have call troubles (such as unilateral audibility, connection
errors), make sure that all the active elements on the VoIP call route
have been set properly. For easy troubleshooting, try the
point–to–point connection with the software IP phone (SJ phone, e.g.)
in your PC and, at the same time, apply network analyzer tracing
).
Refer to
for easy tracing by the BRI gateway.
