Over the next few years, some of the copper connections in the Netherlands will be replaced by fiber optic connections (FTTH – Fiber to the Home) and in the future it is even expected that the majority of these analog connections will be terminated by the cable companies. For a large number of companies, migration to fiber optics will be an excellent solution, but for a significant number of Dutch companies and organizations it will not be a solution, because on the one hand the fiber optic connection is too expensive in comparison with the PSTN subscription, and on the other hand the physical location and that of the connection point can cause problems.


Capestone introduces a unique total solution for the migration of analogue connections to 4G with; CAPESTONE PSTN TO 4G GATEWAY®.

Capestone PSTN to 4G Gateway

Our mission is to make complex technology and solutions accessible to our partners and customers. Anytime, anywhere internet wherever you are, whatever the underlying solution needs to be, that’s what we work on every day. The Capestone PSTN to 4G Gateway has been specifically designed and assembled to easily achieve a future-proof migration of analog networks and connections.

Migrating from PSTN to 4G – Huge market opportunity

There are still many Public Switched Telephone Network (PSTN) networks and connections in the Netherlands, but certainly also in Europe. The analogue endpoint of this network, known as POTS, Plain Old Telephone Service, Post Office Telephone Service or Post Office Telephone System, is still widely used to connect all kinds of equipment and machines. Operators and network owners are increasingly going to end this network service in the coming years to make the migration to fiber. Capestone offers a migration solution based on 4G.

Total solution including hardware, connectivity, service and management

The Capestone PSTN to 4G Gateway is an all-in-one solution to easily migrate analog/PSTN connections to a future fixed solution. The Capestone PSTN to 4G Gateway is an aluminum made enclosure consisting of a combination of IoT hardware, 4G antenna, software and IoT connectivity solutions to receive analog signals, convert them to SIP and then securely transport them over the internet.

Built on A-brands including Cradlepoint/Ericsson, KPN, Cisco and Comgate

The Capestone PSTN to 4G Gateway is put together in collaboration with-and based on-A brands. “Under the hood” runs a robust 4G router from Cradlepoint- part of Ericsson- containing two embedded IoT sim cards from Comgate. This IoT sim solution is primarily based on KPN IoT including Cisco Jasper sim management, the backup sim card concerns a Comgate multi IMSI eSIM including our IoT eConnect sim management portal.

ATA converter & SIP Trunking

The built-in ATA converter is designed to connect analog devices to a VoIP network and is equipped with 2 FXS ports for connecting these analog lines. The ATA also supports the Fax-to-IP protocol (T.38) and 3-way voice conferencing.

Included in the monthly fee of the Capestone PSTN to 4G Gateway is a SIP Trunk subscription with 1x fixed telephone number – which is ported from the analog line – and a call bundle of 250 minutes. Duration of the subscription is 24 months, also available for 36 months.
