OVERVIEW

Multiport VoIP Gateway Routers combine voice and data

traffic for for routing over any IP network.

They enable you to transparently connect up to eight analog phones and fax machines to VoIP. Because these routers work with ordinary analog devices, there’s no need to buy special IP telephones—just use the phones and fax machines you already have.

Models with FXO ports also connect to the local PSTN for backup in case your network connection goes out, so you can call special numbers such as emergency 911.

All models feature dual autosensing 10-/100-Mbps Ethernet ports.

Total VoIP connectivity.

Multiport VoIP Gateway Routers are full-featured VoIP gateways featuring SIP as well as H.323v4 signaling.

They offer up to eight FXS ports and two or four FXO ports. FXS analog ports connect any analog phone or PBX and provide services such as dial-tone, ringing, and Caller ID. FXO ports access the local PSTN for backup.

The routers are smart and adaptable, too! Telephony over IP (ToIP) enables them to handle calls based on variables such as hunt groups, Caller ID, Called ID, and time of day. And of course, they provide all basic phone services such as dial tone and ringing.

The routers provide advanced Quality of Service (QoS) and traffic management. QoS provides clear voice throughput every time by prioritizing VoIP packets on your network. Voice priority and traffic shaping ensure optimal up- and downstream voice quality.

It’s a secure router, too!

VoIP Gateway Routers are capable enterprise routers that connect both voice and data to the WAN through a single secure device. They support full IP routing with IPSEC, PPPoE, DHCP, NAT, and VLAN tagging.

DNS maps domain and host names and IP addresses, enabling you to “hide” your real IP address from the Internet. An access control list enables you to control who can get into your network.

IPSEC VPN sets up secure virtual “tunnels” that protect your data and keep private calls private.

PPPoE encapsulates PPP frames inside Ethernet frames, enabling the router to establish a link from one machine to another over an IP network and then transport data packets over the connection. PPP enables services such as user authentication and usage metering that are missing from the Ethernet protocol.

DES, 3DES, and AES encryption keeps out unwanted users when you send data over the Internet.

Easy setup and management.

VoIP Gateway Routers are quite straightforward to set up. Just connect one of the dual 10/100 Ethernet ports to your LAN. The ports automatically sense and adjust to network speed and duplex as well as cable pinning.

Configure and manage the router through any standard Web browser, SNMP, or through Telnet using a command line interface.

Stay connected to the PSTN.

VoIP Gateway Routers with both FXS and FXO ports (VOE235A–VOE236A, VOE238A) enable you to access your local analog PSTN telephone service as well as your Ethernet nework. The router automatically falls back to your analog voice line if your network goes out.

You can also program the router to choose the PSTN or the network, depending on which number is dialed. This enables you to retain emergency 911 service and to route only certain calls—to your branch offices, for instance—through the IP network. Telephony over IP (ToIP) provides real-time PSTN and VoIP call switching for any PBX, switch, or phone.
