miniCom Virtual Modem
Keep dial-up functionality over IP when PSTN/ISDN disappears – without code changes.

How it works
When the copper network is shut down, many systems still need "modem behaviour". miniCom Virtual Modem emulates classic AT commands and dial-up logic but carries the traffic over IP. Your existing applications keep working without software changes and without the risk of being stuck on outdated PSTN/ISDN infrastructure. The solution is scalable, centralised and can be secured with encryption, authentication and detailed logging. We provide redundant nodes, load balancing and round-the-clock monitoring. You get a modern, reliable layer that mimics the old behaviour while gaining all the benefits of IP-based communication: faster uplink, better error handling and simpler operations.
