 Product Description

The Sangoma IMG 2020 Integrated Media Gateway enables interworking between IP and PSTN networks via high-density optical, telephony, and Ethernet connections in a compact 1U form factor. It transforms media and signalling to support efficient and reliable voice, fax, modem, and tone-based sessions for mobile and cloud-based applications. The IMG 2020 secures sessions across IP and mixed network boundaries in support of service-level agreements.

The combination of a Time Division Multiplexing (TDM) to IP gateway, any-to-any signalling and Session Border Controller (SBC) functionality in a single chassis within the IMG 2020 offers the potential for significant reductions in CapEx and OpEx when compared to less integrated alternatives.

The IMG 2020 Media VoIP gateway is available in:

  • 128 - 768 TDM channels per 1U shelf with Rear I/O Type 1 (scalable from 4 E1/5 T1 to 24 E1/T1)
  • 672 - 2016 TDM channels per 1U shelf with Rear I/O Type 2 (supports either Optical 0C3 interface or 3 DS3s)
  • 100 - 4500 VoIP channels per 1U shelf 50 to 2250 VoIP sessions​​
