VoIP Telephony
Telephoning with VoIP
In addition to the VoIP software client and the audio device, VoIP telephony
also requires a SIP gateway to handle the conversion between IP-based
telephony using the SIP protocol and other telecommunications networks
(e.g. the ISDN network). A SIP gateway can be provided by:
 An SIP provider account: The SIP Gateway is located in the provider
network, the VoIP client registers itself with this gateway via the Internet
(public registration)
 A LANCOM VoIP Router in your local network: The SIP gateway is then
integrated into the router; the VoIP client registers itself with the LANCOM
VoIP Router via the LAN (local registration)
 A VoIP-ready PBX located in the headquarters network: The VoIP client
registers itself with the PBX using a VPN connection (upstream
registration)
The following Quick Start Guide explains how to install the LANCOM VoIP
USB Handset and the LANCOM Advanced VoIP Client as well as how to
configure the client for these three application scenarios.
Further documentation
In addition to these three basic application scenarios, further applications are
presented in the complete LANCOM VoIP solutions documentation.

description of the extensive range of functions and parameters in the VoIP
client software.
