What is a Session Border Controller (SBC) and what is it used for?

An SBC is a specialised network device that secures and controls the transition between different VoIP networks. It protects against SIP-based attacks, normalises protocol differences between PBX systems and SIP trunks, and enables secure integration of Microsoft Teams or Webex into existing telephony infrastructures.

Can AudioCodes help with the migration from ISDN to VoIP?

Yes. AudioCodes Mediant gateways bridge analogue (FXO/FXS), ISDN (BRI/PRI/E1) and digital interfaces with modern SIP trunks. Existing PBX systems and endpoints can continue to be used – without completely replacing the infrastructure.
