FUNC (E)/ Ver 2.00
Description
Enable TLS is the function to switch the session between a SIP Phone Server and the
repeater to TLS.
TLS is a mechanism which can use communications between various server clients using
TCP/ IP as secure communication paths. By enabling Enable TLS, the repeater can
encrypt the SIP session to a SIP Phone Server. This allows information such as the
unique ID used for connection to the SIP Phone Server to be concealed.
Enable
TLS is enabled and the SIP session is encrypted.
Disable
TLS is disabled and the SIP session is normal with the SIP session not encrypted.
Expires is a registration validity period of SIP User ID for the SIP Phone Server by the
repeater.
Before the validity period expires, Registration to a SIP Phone Server is performed by the
repeater.
Maximum Conversation Time is the maximum length of time to maintain the call if a Phone
Call is established between the repeater and SIP server. This timer is used to prevent a
Phone Call from being held for overly long.
Also, if no disconnect request from the transceiver or SIP Phone exists, or if a disconnect
request cannot be received for any reason, the call is disconnected when the timer
expires.
A system administrator can structure a system that suits the operation environment of the
system by configuring this timer. For example, shortening the time of each communication
for the system where congestion frequently occurs allows more users to communicate.
Unlimited
The disconnection of a call is not performed when the length of time elapses.
120 sec to 600 sec
During Phone Call communication, the communication of a Phone Call is disconnected
when the length of time configured in Maximum Conversation Time elapses and PTT for
the transceiver or Console is released.
When the length of time configured in Maximum Conversation Time elapses and the
transceiver or Console is transmitting audio, the communication of a Phone Call is
disconnected after PTT is released.
If no response is received for a certain length of time from the transceiver or Console after
a Phone Call is established between the repeater and SIP server, the call is disconnected
when the timer expires.
