Reset Button - ZyXEL Communications P-2302R-P1 Series User Manual

Reset Button

The ZyXEL Device reset button is built into the rear panel. Use this button to restore the
factory default password to 1234; IP address to 192.168.1.1, subnet mask to 255.255.255.0
and DHCP server enabled with a pool of 32 IP addresses starting at 192.168.1.33.
Multiple Telephones
You can connect more than one telephone to a ZyXEL Device telephone port. The Ringer
Equivalence Number (REN) is used to determine the number of devices that may be connected
to the telephone line. See the
PSTN Line (P-2302RL-P1 only)
The ZyXEL Device allows you to connect a PSTN line. You can receive incoming PSTN
phone calls even while someone else connected to the ZyXEL Device is making VoIP phone
calls. You can dial a (prefix) number to make an outgoing PSTN call. You can still make
PSTN phone calls if the ZyXEL Device loses power.
Dynamic Jitter Buffer
The ZyXEL Device has a built-in, adaptive buffer that helps to smooth out the variations in
delay (jitter) for voice traffic. This helps ensure good voice quality for your conversations.
Multiple SIP Accounts
The ZyXEL Device allows you to simultaneously use multiple voice (SIP) accounts and
assign them to one or more telephone ports.
STUN
Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators
(STUN) allows SIP to pass through NAT routers.
Outbound Proxy
Some VoIP service providers use a SIP outbound server to handle voice calls. This allows the
ZyXEL Device to work from behind any type of NAT router and eliminates the need for
STUN or a SIP ALG (Application Layer Gateway).
Multiple Voice Channels
The ZyXEL Device can simultaneously handle multiple voice channels (telephone calls).
Additionally you can answer an incoming phone call on a VoIP account, even while someone
else is using the account for a phone call.
