Keepalive; Filetransfer - Polycom CX5100 Administrator's Manual

RTP Port Parameters (continued)
Parameter
The starting port for RTP packets. Ports are allocated from a pool starting with this port up to a value of (start-port +
47) for a voice-only system or (start-port + 95) for a video system.
Note: Ensure that there is no contention for port numbers. For example, do not use 5060 (default port for SIP).
1 Change causes system to restart or reboot.
<keepalive/>
The parameters listed in the next table enable the configuration of TCP keep-alive on SIP TLS connections;
the system can detect a failure quickly (in minutes) and attempt to re-register with the SIP call server (or its
redundant pair).
TCP Keep-Alive Parameters
Parameter
tcpIpApp.keepalive.tcp.idleTransmitInterval
The amount of time to wait (in seconds) before sending the keep-alive message to the call server.
Note: If this parameter is set to a value that is out of range, the default value is used.
Note: This parameter specifies the number of seconds TCP waits between transmission of the last data packet and
the first keep-alive message.
tcpIpApp.keepalive.tcp.noResponseTransmitInterval
If no response is received to a keep-alive message, subsequent keep-alive messages are sent to the call server at
this interval (every x seconds).
Note: This parameter specifies the amount of idle time between the transmission of the keep-alive packets the TCP
stack waits. This applies whether the last keep-alive was acknowledged or not.
tcpIpApp.keepalive.tcp.sip.tls.enable
If 0, disable TCP keep-alive for SIP signaling connections that use TLS transport. If 1, enable TCP keep-alive for SIP
signaling connections that use TLS transport.
1
Change causes system to restart or reboot.
<fileTransfer/>
The parameters listed in the next table configure file transfers from the system to the provisioning server.
File Transfer Parameters
Parameter
tcpIpApp.fileTransfer.waitForLinkIfDown
If 1, file transfer from the FTP server is delayed until Ethernet comes back up.
If 0, file transfer from the FTP server is not attempted.
