56 VoIP Subscriber Gateways
Common settings
SIP configuration:
- STUN enable – STUN (Session Traversal Utilities for NAT) is used during initialization of
STUN server in the network to determine public address (the device external gateway
address);
STUN server address (:port) – IP address or domain name of STUN server.
Alternative server port can be assigned after colon (the default value is 3478);
STUN request sending interval (sec) – STUN request sending interval. The less
polling interval then higher speed of reaction on the public address changes;
- Public IP – the parameter is used as external device address during work on NAT (on
gateway). This parameter is used as a public address of gateway (NAT) WAN interface on
which TAU-8.IP is set up. At that, SIP and RTP port forwarding is required (these ports
are used by TAU-8.IP);
- Disable NAPTR DNS queries – in some cases, when DNS operates incorrectly, NAPTR
queries (Naming authority pointer) may cause negative result. When flag is set, these
queries will be disabled;
- Disable SRV DNS queries – in some cases, when DNS server operates incorrectly, SRV
requires may cause negative result. When flag is set, automatic queries will be disabled;
- Invite initial timeout (ms) – time interval (in milliseconds) between the first INVITE
message transfer and the second INVITE message transfer when the first message is
unanswered. This interval will be doubled for the next INVITEs (third, fourth and
etc.).(For example, if the second INVITE will be transferred after 300 ms, the third will
be transmitted after 600 ms, the fourth - after 1200 ms and etc.);
- Retransmission interval for nonINVITE requests (ms) – time interval in milliseconds
between the first nonINVITE message transfer and the second nonINVITE message
transfer when the first message is unanswered. This interval will be doubled for the next
