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
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: Bizfon 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 you to choose between regular DNS servers configured in the
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 Bizfon.
•
Custom allows manually defining the Registration Timeout, Registration Failure Timeout, Transaction Duration and Session refresh
timeout SIP timers (in seconds).
