An audio broadcasting function for PTT service is core technologies of PTT server function. It performs broadcasting function of audio information which is transmitted from IP terminal in each group End-Point and each session End-Point and broadcast to the each group or to the entire IP terminal. PTT service causes a lot of load because it has to broadcast real time audio information to the different IP terminal so it requires high performance processing. AddPac IPNext180PTT IP-PBX is designed on the basis of high performance embedded RISC which supports medium scale PTT service. It is an ideal product for medium size corporation and support Push-to-Talk service by interworking with AddPac LMR gateway, WiFi phone, and various PTT IP phone products.

RTP Proxy Service Features for Private IP and IPv6 Address

Since the enterprise network environments configured with a Call Manager like as Hybrid IP-PBX system and IP terminals require larger number IP address, either IPv6 or a private IP address in the NAT environment must be supported to the enterprise networks due to the deficient resources of a public IP address. In such a private IP address environment, the RTP proxy feature is required for reliable multimedia communications between endpoint terminals. The RTP proxy feature of IPNext180PTT is used to make a communication between a private IP terminal and a public IP terminal among endpoint terminals such as IP phones, make a communication between a private IP terminal and a public IP terminal in the NAT environment, make a communication between private IP terminals, make audio/video broadcasting in private and public IP environments, and to enable audio/video conference calls in private and public IP environments. The RTP proxy feature can operate regardless of VoIP signaling protocols such as H.323 and SIP, and supports dual address systems such as IP version 4 and IP version 6addresses.

Intelligent IVR Features

One of the most important IP telephony service features is either ARS or IVR. Different IVR features are required by regular companies, government offices, and call centers respectively. IPNext180PTT Hybrid IP-PBX System provides an IVR tool to meet your requirements. Also, this solution provides an IVR scenario editor to allow you to make and enable a desired call scenario.

User Presence Service for Unified Communication

For enterprise with small number of employee, IPNext180PTT Hybrid IP-PBX system supports the userpresence server function beside call manager function. But, in case of large enterprise, external User Presence Server should be used with IP-PBX due to performance issue independently.In order to support user presence features on real-time basis, such as user busy, on-line, user away,etc, user presence service function should be provided on IP telephony solution.User presence service function in a Call Manager gathers user information (on-line, busy, etc) of each IP terminals, and broadcasts user information to all or group IP terminals with speed-dial keys (built-in presence indication lamp) , AP-PT100 User Presence dedicate terminal, Smart Messenger Program at every second.
