Description
This field is new in Firmware Release 5.0.
Indicates if the failover should start when the time expires and
the corresponding SIP transaction fails.
This field is new in Firmware Release 5.0.
Indicates the keep alive mechanism for calls. This specifies the
maximum time between session refresh signals. When the phone
is on a call and it doesn't send a session refresh signal in the
configured time, the call terminates.
If disabled, session timers aren't used.
Indicates the length of time in seconds for the SIP Session Timer.
Indicates the protocol for SIP transport.
• UDP: Enforce the use of SIP over UDP. If an NAPTR lookup
succeeds and returns entries, then only SIP/UDP entries are
used.
• TCP: Enforce the use of SIP over TCP. If an NAPTR lookup
succeeds and returns entries, then only SIP/TCP entries are
used.
• TLS: Enforce the use of TLS over TCP. If an NAPTR lookup
succeeds and returns entries, then only SIPS/TCP entries are
used.
• Auto: A NAPTR lookup must succeed. The order (normally
TLS, TCP, UDP) of the entries from the DNS NAPTR lookup
is taken into account. TLS, TCP, and UDP are all accepted.
SCTP is not accepted.
Indicates if the source port needs to be explicitly signaled in the
SIP messages.
When SIP Transport is set to TCP or TLS, a connection is
established for each SIP extension. The source port of the
connection is chosen by the TCP stack, and the local SIP port
parameter is not used.
