Voip Configuration - ZyXEL Communications P-2612HNU-Fx Support Notes

This behavior is normal, because the CPE itself can also be accessed by FTP, on port
21. Since we are creating a new rule using port 21, the default port number of the
CPE' s FTP server will automatically change to 2121.
A new port forwarding rule is now created.

VoIP Configuration

Setting up an SIP Account
The VoIP technology sends voice signals over the Internet Protocol. This allows users
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 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 Prestige can hold up to two SIP
account simultaneously. P lease follow the instructions below to configure the SIP
accounts properly.
Note: You should have a voice account already set up and have VoIP information
from your VoIP service provider prior to configuring a SIP account on the unit.
With the account information supplied by your ITSP provider at hand you may start
the setup procedure.
1. Go to VoIP>SIP, click on "SIP Service Provider" and enter the SIP server IP
address supplied by your SIP service provider. Leave the Advanced setting
unchanged.
