Asterina - PSTN (ISDN) Gateway

Anyone intending to join the VoIP-world but not wanting to totally dispense with the functionality of ISDN can optionally realize a large combination of external connections with our Asterina Channel Box.

  • max. 8xS0 / 4xE1 and conbinations
  • max. 8xFXO / 8xFXS and combinations
  • max. 4xGSM

Thus connections to the public ISDN-net as well as existing ISDN-extension lines can be realized together with POTS landlines and legacy phones.

In conjunction with the LCR-module and the ISDN-connection routing algorithms can be accomplished which can use the ISDN-connectivity as last fallback.
