Multiple Channel Technology and Multiple SIP Phone Numbers Freely Assignable to Two Phone Ports
The single box serves 2 communication lines simultaneously; and its concurrent G.729 capability on each phone port is a great solution for environments with limited bandwidth. The flexible dial mechanism and one or two communication lines can be assigned freely to 2 phone ports.

NAT Router Capability Integration
The P-2302RL-P Series is an inexpensive, easy to install and use, clutter-free solution to broadband users connecting to the Internet or a local area network. The users can also effortlessly configure the routing/bridge mode with WebGUI according to environment needs.

Rich Call Features
A number of sophisticated call features are engineered into the ZyXEL VoIP device. Users can perform the related features such as call forwarding, call transfer, three way conference call, etc. with just WebGUI and keypad.

Effective Network Bandwidth Management and State-of-the-Art Security Firewall
The VoIP device enables network administrators to allocate network resources while guaranteeing Quality of Service (QoS). Network Bandwidth Management enhances productivity and efficiency by tailoring a system to specific demands such as time-sensitive VoIP and multimedia applications. Based on Stateful Packet Inspection and Denial of Service (DoS) technology, the ICSA-certified ZyNOS operating system provides the first line of defence against hackers, network intruders, and other hazardous threats.

 

Easy Provisioning Management of TR-104* (customizable)

On ZyXEL TR-104, the VoIP CPE Provisioning parameter defines a VoIP CPE device provisioning data model established by an Auto-configuration Server (ACS) using the mechanism.
