VoIP Application Notes
Setup SIP Account
VoIP is the sending of voice signals over the Internet Protocol. This allows you to make phone calls and send
faxes over the Internet at a fraction of the cost of using the traditional circuit-switched telephone network.
The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that handles the setting
up, altering and tearing down of voice and multimedia sessions over the Internet. SIP signaling is separate from
the media for which it handles sessions. The media that is exchanged during the session can use a different path
from that of the signaling. SIP handles telephone calls and can interface with traditional circuit-switched
telephone networks.
The ZyXEL Device can hold up to two SIP account simultaneously please follow the below instruction to
configure the SIP account properly.
