Port/><Rtp - Polycom CX5100 Administrator's Manual

● Stop DST on the first Sunday in November at 2am.
Simple Network Time Protocol (SNTP) Parameters
Parameter
tcpIpApp.sntp.address
The address of the SNTP server.
tcpIpApp.sntp.AQuery
If set to 0, queries to resolve the SNTP hostname are performed using DNS SRV. If set to 1, the host name is queried
for a DNS A record instead.
tcpIpApp.sntp.address.overrideDHCP
If 0, the DHCP values for the SNTP server address are used. If 1, the SNTP parameters override the DHCP values.
tcpIpApp.sntp.retryDnsPeriod
Set a retry period for DNS queries. Note that the DNS retry period you configure is affected by other DNS queries
made by the system. If the system makes a query for another service such as SIP registration during the retry period
you configure and receives no response, the Network Time Protocol (NTP) DNS query is omitted to limit the overall
number of retry attempts made to the unresponsive server. If no other DNS attempts are made by other services,
then the rety period you configure is not affected. If at any time the DNS server becomes responsive to another
service, then NTP also immediately retries its DNS query as well.
<port/><rtp/>
The parameters listed in the next table enable you to configure the port filtering used for RTP traffic.
RTP Port Parameters
Parameter
tcpIpApp.port.rtp.filterByPort
Ports can be negotiated through the SDP protocol. If set to 1, the system rejects RTP packets arriving from (sent
from) a non-negotiated port.
tcpIpApp.port.rtp.forceSend
Send all RTP packets to, and expect all RTP packets to arrive on, this port. If 0, RTP traffic is not forced to one port.
Note: Both tcpIpApp.port.rtp.filterByIp and tcpIpApp.port.rtp.filterByPort must be set to 1
for this to work.
tcpIpApp.port.rtp.mediaPortRangeEnd
Determines the maximum supported end range of audio ports.
tcpIpApp.port.rtp.mediaPortRangeStart
