Default Value Description
60 Registration Timeout is the optional timeout for SIP account
registration, in seconds. The maximum is 604800, which is 7 days.
300 Configure auto re-registration retry interval in seconds. If SIP
registration is unsuccessful, this property specified the time
duration between retry attempts in seconds.
1 Specify the preference for using SIP session keep-alive timers.
1800 (30 The expiration period (seconds) is the interval at which the phone
minutes) will consider the SIP session timed out if it does not receive a
refresh message from the remote phone. It is measured in seconds
and must be greater than 90.
90 SIP session timer minimal expiration period (seconds). This is the
minimum period that the device will accept when negotiating the
expiration period with the remote phone. If the session timer
expiration duration is less than this value, this value is used
instead. It is measured in seconds.
0 Implements reliable SIP provisional responses. SIP is a request-
response type of protocol with two types of responses: provisional
and final. Final responses are sent reliably, using an ACK to ensure
receipt. Provisional responses by default are not sent reliably and
do not require an ACK; however, in some cases, such as for PSTN
interoperability support, reliability of provisional types of
responses is needed. Choose this option to add the PRACK
(provisional ACK) message support for reliability.
1 Configure whether SIP traversal behind NAT is disabled. Used for
device behind a symmetric NAT (Network Address Translation).
When enabled, the device will keep track of the public IP address
from the response of the REGISTER request. If it detects that the
address has changed, it will unregister the current Contact, update
the Contact with the transport address obtained from the Via
header, and register a new Contact to the SIP registrar. This option
will also update the public name of the UDP transport if STUN is
configured.
