5.2.3 The Local Area Network

To share voice and data properly, your network requires an Ethernet switch. A switch isolates the Ethernet ports from each other and only allows traffic intended for the device connected to that port to ensure that data traffic doesn’t compete with voice traffic. A router is required to separate voice and data traffic (different subnets) successfully.

Example: The Linksys BEFSR81 router has a built-in 8 port switch which is perfect for a LAN supporting both TalkSwitch units and computers. If you’re not certain whether your equipment is an Ethernet switch, contact the manufacturer.

5.3 FAQ

How does VoIP work?

Voice over IP, or VoIP, sends calls over the Internet or any Internet Protocol (IP) network by converting voice traffic into data packets. These packets are routed over the IP network in the same way as other data, reassembled at the point of arrival and converted back to voice.

Does a VoIP call sound like a regular phone call?

Under the right conditions, VoIP calls can sound as good or even better than regular phone calls. Voice quality is affected by numerous issues, including how it is compressed for delivery over the Internet, decompressed and how packets are processed. A few steps can help ensure call quality.

1.High-speed connections on both ends of the call

Good quality VoIP is not possible over a dial-up modem connection. A broadband connection is required to support more simultaneous VoIP calls. Please visit our site at www.talkswitch.com/voip/voip_test.php to determine what your Internet connection can support.
