92 9600 Series SIP IP Telephones Administrator Guide SIP Release 2.0
TCP_KEEP_ALIVE_TIME 60 This time interval is the time 9600 Series SIP IP
Telephones will wait before sending out a TCP keep-alive
message (TCP ACK message) to the far-end. The time is
controlled by the system's TCP/IP stack. The timer is
restarted after application level data (for example, a SIP
message) is sent over the socket. When the system is
idle, this keep-alive time expires and results in sending a
TCP ACK (keep-alive) packet. Valid values are 10-3600
(seconds).
TIMEFORMAT 0 Display time according to defined format in the top line
and in the call log. Values are:
0=am/pm format
1=24h format
TLSDIR " " (Null) Path name for https downloads. Character string of 0 to
127 characters representing a directory name or path to
directory.
TLSPORT 443 Destination TCP port used for requests to https server
during initialization. Values: 0-65535.
TLSSRVRID 1 Flag to indicate if TLS server identification is required.
Valid values are:
0 = no certificate match necessary; TLS/SSL connection
will be established anyway.
1 = certificate match required; TLS/SSL connection will
only be established if the server's identity matches the
server's certificate.
TRUSTCERTS " " (Null) File names of certificates to be used for authentication.
List of file names separated by commas (0 to 1024
characters).
USE_EXCHANGE_
CALENDAR
0 Activate/deactivate usage of calendar on Microsoft
Exchange™ Server. Values are: 0=disabled, 1=enabled.
USE_QUAD_ZEROS_
FOR_HOLD
0 Flag that indicates whether a= directional attributes or
0.0.0.0 IP Address is used in the SDP to signal hold
operation. 0=use “a= directional attributes”, 1=use quad
zeros.
VLANSEP 1 Enables or disables VLAN separation. Controls whether
frames to/from the secondary Ethernet interface receive
IEEE 802.1Q tagging treatment. The tagging treatment
enables frames to be forwarded based on their tags in a
manner separate from telephone frames. If tags are not
changed, no tag-based forwarding is employed. Values
are: 1=On/Enabled, 2= Off/Disabled. This parameter is
used with several related parameters. For more
information, see VLAN Separation
on page 96.
VLANTEST 60 Number of seconds to wait for a DHCPOFFER when
using a non-zero VLAN ID (1-3 ASCII digits, from “0” to
“999”).
