Introduction
The IPTEL-H / IPTEL-S / IPTEL-M is a single port Telephone Adaptor (TA) for Voice over
IP (VoIP), and it supports H.323, and SIP (optional) Protocols. Connecting to the Internet
with a plain old telephone set (POTS), the IPTEL can make a voice call over the Internet
from one IP to another one.
With additional PC LAN port comparing to IPTEL, the IPTEL allows connection to a
Notebook PC when using in the office. With portable and user friendly design, the
IPTEL-H / IPTEL-S / IPTEL-M is very suitable for ITSP (Internet Telephony Service
Providers) customers and SOHO users to make a voice call on the Internet.
Note that each IPTEL-H / IPTEL-S / IPTEL-M will need an IP address, a subnet mask,
and its gateway IP address for its own use. These three are available from your
Internet service provider. The Media Access Control (MAC) hardware address is
indicated at the bottom of IPTEL-H / IPTEL-S / IPTEL-M.
