For SME customers and smaller offices the perfect VoIP solution
consitst of an IAD (internet access device) or access router with
integrated VoIP gateway functionality.
Good devices offer all the IP routing, NAT, security and management
functions to provide Internet access for one or more computer systems
in the local network. Additional QoS features and the necessary server
and gateway functions allow the customer to quickly configure a
complete VoIP (LAN Telephony, IP Telephony, Internet Telephony)
solution. These VoIP IADs will support one or several of the VoIP
standards (H.323, SIP, MGCP, etc).
Some of these devices will support an additional ISDN or analogue
PSTN telephone connection. This allows the user to alternatively use
this connection in case of a problem with the Internet connection or to
use special voice services that are not available from within the VoIP
network. The user can define in a dialing plan which numbers should be
routed into either the PSTN or the VoIP (Internet, etc.) network
For users that wish to use existing analogue devices (telephones, DECT
wireless phones, fax machines, etc) in their VoIP solution, some access
devices have integrated VoIP adapters that provide one (or more)
analogue ports.
