Frequently Asked Questions
If you do not understand a term or acronym, check the Glossary.
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 Ye s. 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 Ye s. 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.
