The
UDP Port
indicates the SIP UDP (User Datagram Protocol)
receive port number. By default 5060 is selected and used. The SIP
UDP port cannot be in the selected RTP/RTCP port range for IP lines
(see
), otherwise the “Mapped port for SIP shouldn’t be
in RTP port range” error message appears.
The
TCP Port
indicates the SIP TCP (Transmission Control Protocol)
receive port number. By default, 5060 is selected and used.
Please Note:
QX1000 will not use TCP protocol as a transport for
SIP messages if the
TCP
Port
field is left empty.
The
TLS Port
indicates the SIP TLS (Transport Layer Security)
receive port number. By default, TLS port is not used and is empty
(coded to 0).
TLS port
number should be different from the
TCP Port
number.
The
Realm
text field requires messaging level information to be
included in SIP messages sent by QX1000. This information might
be used by remote side for authentication purposes.
Enable Session Timer
enables advanced mechanisms for
connection activity checking. This option allows both user agents and
proxies to determine if the SIP session is still active.

The
DNS server for SIP
radio button group allows you to choose between regular DNS servers configured in the
page and specific
DNS servers for SIP traffic.
•
Use default
is used to apply regular DNS servers for SIP traffic.
•
Specific
is used to enable SIP specific DNS servers. For this selection, both primary and secondary SIP DNS servers should be defined in
the
SIP DNS 1
and
SIP DNS 2
text fields. At the least, a primary DNS server should be inserted.
The
SIP Timers
radio button group is used to define the timeouts of the SIP messages retransmission.
•
RFC 3261
will apply standard SIP timers described in the corresponding specification.
•
High availability
will apply SIP timers to shorten the call establishment, registration confirmation and registration failure procedures. This
selection provides more firmness to the SIP connection but increases the network traffic on the QX1000.
•
Custom
allows manually defining the
Registration Timeout
,
Registration Failure Timeout
,
Transaction Duration
and
Session refresh
timeout
SIP timers (in seconds).

Host aliases for SIP
This page is used to create a list of QX1000's hostnames
register on remote DNS servers. This list will be used to identify
SIP packets received from remote servers where QX1000 is
registered with different names.
The
Host aliases for SIP
page
consists of a table where
QX1000's aliases are listed. Add opens the
Add Entry
page
where a new alias name for QX1000 should be defined.
