Q
What does the Motorola voice terminal do?
A
The
VT2400/VT2500 Voice Gateway
is part stand-alone media terminal adapter (S-MTA) and part home
broadband router:
•
As an S-MTA, it converts analog voice signals to and from a standard telephone to digital data that can
be transmitted through a broadband connection across the Internet. It provides an alternate means to
make voice calls.
•
It provides basic routing to enable simultaneous voice and data communication.
Q
Will the
VT2400/VT2500 Voice Gateway
work with a cable modem or DSL modem?
A
Yes. The
VT2400/VT2500 Voice Gateway
supports
DHCP
, which is specified for
DOCSIS
cable modems,
and
PPPoE
, which is used by most DSL providers.
Q
Can end users operate a virtual private network (VPN) application behind the
VT2400/VT2500
?
A
Yes. The
VT2400/VT2500 Voice Gateway
supports
IPSEC
and
PPTP
, the most common VPN protocols.
Q
Can the end user play online games through their
VT2400/VT2500
?
A
By default, the
VT2400/VT2500 Voice Gateway
blocks all unsolicited messages to the computer or end-user
network as a standard security measure. However, for online games that require some unsolicited messages
to be transmitted through the
VT2400/VT2500
, the end user can specify ports and IP addresses on which to
allow unsolicited messages. The
VT2400/VT2500 Voice Gateway
enables the end user to set up virtual
servers or a
DMZ
.
Q
How does the end user configure the
VT2400/VT2500
?
A
Most end users who perform the appropriate installation procedure in “
Connecting the VT2400/VT2500 to a
Network
”
can send and receive calls immediately!
Configuring your home or office network is done through
a GUI where configuration options are selected using a connected PC configured to use DHCP to obtain its
network IP address (see
“Gateway > WAN — DHCP Client”
on page 34). Or, the user can configure the
computer statically to 192.169.102.
xxx
(
xxx
is from 2 to 254), subnet 255.255.255.0, and default gateway
192.168.102.1 (see
“Gateway > WAN — Static”
on page 36). Or, the user can configure a DSL connection
by using the PPPoE Client configuration method (see
“Gateway > WAN — PPPoE Client”
on page 35).
Q
What is included with the built-in Ethernet router and wireless access point?
A
The
VT2400/VT2500 Voice Gateway
supports a firewall, RIP, parental control, port triggers, advanced
ALGs such as RSVP, POP3,
SNMP
, and streaming media. No separate routers or wireless access points are
needed.
Q
Is any Quality of Service (QoS) implemented on the
VT2400/VT2500 Voice Gateway
?
A
Although VoIP service is typically best-effort, the
VT2400/VT2500
provides upstream voice prioritization
to ensure that upstream voice data has priority over other Web data. This ensures good voice quality even
during heavy upstream data transfers, such as e-mail synchronization or file sharing.
