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.
