ARRIS 9.x 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 pre-
cluded 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.
Certain ARRIS Gateway models have one or more voice ports for connecting telephone handsets. These mod-
els support VoIP. If your Gateway is a VoIP model, you can configure the VoIP features.
VoIP Profile Settings
set voip profile [ 1 - 4 ] prof-enable [ on | off ]
Enables or disables the use and configuration of the specified VoIP profile on the ARRIS® Gateway.
set voip profile [ 1 - 4 ] proxy-server
address
Specifies the IP address or fully-qualified domain name of the SIP proxy server that stations using the profile
will connect to.
set voip profile [ 1 - 4 ] proxy-port
port
Sets the well-known port number the station using the profile will use to connect to the SIP proxy. Default is
5060
.
set voip profile [ 1 - 4 ] proxy-transport udp
Assigns a proxy transport protocol to the VoIP profile. Default is
udp
.
set voip profile [ 1 - 4 ] registrar-server
address
Specifies the IP address or fully-qualified domain name of the SIP registrar (server) that stations using the pro-
file will connect to.
set voip profile [ 1 - 4 ] registrar-port
portnumber
Sets the well-known port number the user agent using the profile will use to connect to the SIP registrar.
Default is
5060
.
set voip profile [ 1 - 4 ] registrar-transport [ tcp | udp | tls ]
Assigns a registrar transport protocol to the VoIP profile. Default is
udp
.
set voip profile [ 1 - 4 ] sip-expires [ 0 – 65535 ]
Specifies the SIP registration server time-out duration from 0 – 65535 seconds for the specified profile. Default
is
3600
(1 hour).
