Moving voice calls from ISDN to SIP Services is a tried and tested way of saving money on both trunk rentals and telephone call charges and with the BT PSTN Network Switch-Off locked in for 2025 and End of Sale in 2023 it has never been more important to start moving to a SIP-based solution today.
GreenCity Solutions partner closely with Gamma Telecom for our SIP Trunk Solutions. Gamma Telecom are one of the largest network operators in the UK, with a reputation built on technical expertise and voice service delivery, they have an in-depth experience of VoIP implementations, working with organisations of all sizes.

YES! We can port your existing landline numbers (01, 02) from your current service to a SIP solution so you can continue to receive calls on those numbers.
With SIP Trunk Call Manager we also have support for Non-Geographic Numbers (NGN) such as 03, 08, etc.
BT will shutdown the PSTN (Public Switch Telephone Network) in 2025 but will stop selling any services related in 2023. However trials in certain locations are happening as early as December 2020.
Any legacy PSTN services (such as ISDN) still live after the switch-off will be ceased. It is imperative to move to alternative services before this happens in order to avoid loss of service.
Check out our ISDN to SIP Converters which enable the ability to use SIP on Legacy Phone Systems that it isn’t currently possible to replace.
