Panasonic KX-TDA5480 4 Channel VoIP Gateway Card | New

The Panasonic KX-TDA5480 4 Channel VoIP Gateway Card (also known as IPGW4) is a specialized expansion card designed to bring Voice over IP (VoIP) capabilities to Panasonic's KX-TDA50 and KX-TDA50G hybrid IP PBX control units.

The Panasonic KX-TDA5480 4 Channel VoIP Gateway Card (also known as IPGW4) is a specialized expansion card designed to bring Voice over IP (VoIP) capabilities to Panasonic's KX-TDA50 and KX-TDA50G hybrid IP PBX control units.

Its primary function is to act as a gateway between the traditional PBX system and an IP network, allowing the PBX to establish and manage calls over the internet.

Key Features:

• VoIP Gateway Functionality: The core purpose of this card is to convert voice signals from the traditional telephony system (TDM) into IP packets for transmission over a data network, and vice versa. This enables the use of VoIP for both internal and external communications.
• 4 IP Connections/Channels: The card provides four simultaneous VoIP channels.This means it can handle up to four concurrent VoIP calls, whether they are internal calls between IP extensions, or external calls made/received via a VoIP service provider (SIP trunks) or other networked KX-TDA systems.
• Networking Multiple PBXs: A key application is to network multiple Panasonic KX-TDA50/50G systems together via an IP network. This allows for seamless communication and extension dialing between different office locations (e.g., a branch office in Fairfield, New Jersey, connecting to a main office elsewhere) without incurring traditional long-distance charges.
• SIP Trunk Support: The card supports SIP (Session Initiation Protocol), which is the industry standard for VoIP communication. This allows businesses to connect their KX-TDA50/50G system to SIP trunking services from VoIP providers, offering potentially significant cost savings on traditional phone lines and long-distance calls.
• Protocol Compliance: It is compliant with various international standards, including:
  • H.323V.2: A common standard for multimedia communication over IP networks.
  • ITU-T G.729a, G.723.1, and G.711:These are voice codecs, which define how voice is compressed and decompressed for transmission over IP. G.711 offers high quality, while G.729a and G.723.1 offer more compression for lower bandwidth usage.
• Compatibility: Explicitly designed for the Panasonic KX-TDA50 and KX-TDA50G hybrid IP PBX control units. It will not work with other Panasonic PBX series unless explicitly stated.
• Installation Limit:Typically, only one KX-TDA5480 card can be installed per KX-TDA50/50G system, providing a maximum of 4 IP channels per system for gateway purposes. (Some sources might indicate support for 2 cards in certain KX-TDA models, but for the TDA50/50G, 1 card is generally the maximum for this specific gateway type).
• Remote Programming Capability: In some configurations, this card can also facilitate remote programming and maintenance of the KX-TDA50 PBX over the network, simplifying IT management.
• No Video Support: While it enables VoIP, this card is primarily designed for audio VoIP calls and typically does not support video conferencing features.
