SIP Settings
The
SIP Settings
provide information on the SIP receive UDP and TCP ports and allows you to select DNS server configurations for SIP and the SIP timers
scheme.
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 FXS
and IP lines (see RTP Settings ), 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:
QX 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 QX. This information might be
used by remote side for authentication purposes.
Fig.II- 90: SIP Settings page
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 DNS Settings 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.
