Voip Commands - Motorola nvg589 Administrator's Hanbook

set security spi flood-limit udp enable [ off | on ]
Enables or disables whether UDP packet flooding should be detected and offending packets be dropped. Defaults
to off.
set security spi flood-limit tcp enable [ off | on ]
Enables or disables whether TCP packet flooding should be detected and offending packets be dropped. Defaults
to off.
set security spi flood-limit tcp syn-cookie [ on | off ]
Allows TCP SYN cookies flooding to be excluded. Defaults to on.
Reflexive ACL
set security spi ip6 allow-inbound [ on | off ]
Turns reflexive ACL on or off for IPv6.
Reflexive Access Control Lists (ACL) provide that layer 4 Session information is used to make decisions about
what packets to route. Reflexive ACL reduces exposure to spoofing and denial-of-service attacks, because
desired inbound packet flows are usually in response to outbound traffic.
Motorola 9.x DSL Gateways use the relevant session information about whether the packet flow was initiated from
the LAN side (upstream) or WAN side (downstream). If the parameter security.spi.ip6.allow-inbound is set to off,
then sessions which are initiated from the WAN side are disallowed. Upstream sessions are never precluded
because of reflexive ACL. (Of course there may be other reasons that particular packets are dropped.)
For IPv4, NAT is generally enabled, so reflexive ACL is usually not an issue.

VoIP commands

(supported models only}
Voice-over-IP (VoIP) refers to the ability to make voice telephone calls over the Internet. This differs from tradi-
tional phone calls that use the Public Switched Telephone Network (PSTN). VoIP calls use an Internet protocol,
Session Initiation Protocol (SIP), to transmit sound over a network or the Internet in the form of data packets. Cer-
tain Motorola Gateway models have one or more voice ports for connecting telephone handsets. These models
support VoIP. If your Gateway is a VoIP model, you can configure the VoIP features.
set voip phone n sip-option [ off | on ]
Turns SIP on or off for the phone specified by n , usually 1 or 2, depending on your Gateway's number of physical
voice ports. Default is off.
set voip phone n sip-proxy-server [ server_name | ip_address ]
Specifies the SIP proxy server for the specified phone by fully qualified server name or IP address.
set voip phone n sip-proxy-server-port [ 1 - 65535 ]
Specifies the SIP proxy server port number for the specified phone. Default is 5060.
set voip phone n sip-proxy-server-transport [ udp | tcp ]
Specifies the SIP proxy server transport protocol for the specified phone. Default is UDP.
