SIP Settings
The
SIP Settings
provide information on the SIP receive UDP and TCP ports and allows to select DNS server configuration for SIP and SIP timers
scheme.
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
), otherwise the “Mapped
port for SIP shouldn’t be in RTP port range” error appears.
TCP Port
indicates the SIP TCP (Transmission Control
Protocol) receive port number. By default 5060 is selected and
used.
Please Note:
Quadro will not use TCP protocol as a transport
for SIP messages if the
TCP
Port
field is left empty.
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 to choose between regular DNS servers configured in the
page and specific DNS
servers for the SIP traffic.
•
Use default
is used to apply regular DNS servers for the 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 Quadro.
•
Custom
allows defining manually the
Registration Timeout
,
Registration Failure Timeout
,
Transaction Duration
and
Session refresh
timeout
SIP timers (in seconds).
