Basic parameters
Port – is a local port of NetSpeaker Server on which the given gateway is
communicating with the counterparty.
Realm(Domain) – define the domain over which this gateway is
communicating. The domain and port specified here are relevant for subsequent
call routing to the NetSpeaker Server. The Request–URI field including
Realm(Domain) + port are checked for incoming INVITE messages. If the values
match the SIP GW setting, the packets are routed to the NetSpeaker Server. The
INVITE messages are served too whose Request–URI values are included in the
Aliases
Via/Contact header – define the contents of the Via and Contact headers. The
following options are available:
Connect to – fill in the unique PBX IP address.
FQDM – the header includes the PBX Host Name, which can be filled on the PBX
IP interface.
NAT – fill in the fixed public IP address and NAT port to which signalling
messages for the PBX should be sent by the counterparty. Packets are routed to
the PBX based on the set port routing IP address on the router.
STUN – fill in the STUN server address and port to identify the current address
behind the NAT router.
Requires authorisation – activate authorisation request for incoming calls from
the counterparty. User login data are used for call authorisation. All logins are

network when the counterparty hangs up.
Remote SIP server parameters
Address – set the IP address or DNS name of the counterparty (operator or
another PBX) to which you want to connect the PBX via a trunk (where call and
registration requests shall be routed). To use a port other than 5060, specify the
port behind the colon (192.168.122.43:5071).
Protocol – specify whether UDP and/or TCP shall be used for transmission. If
you choose NAPTR (Name Authority PoinTeR), a query to the DNS is made first
and, depending on the reply, the proper transmission protocol is set. The Use
DNS SRV
Register line – enable registration with the counterparty and specify the
gateway registration number (Caller ID). No call setup requests can be resent to
an unregistered gateway.

by the counterparty (if shorter).
