•
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).
