Lines & Calls

Many organisations are suggesting PSTN and ISDN lines will be withdrawn next year.  This is not true, confirmed by a recent Openreach quote, below;

Openreach is consulting with industry around the process and timeline for the withdrawal of wholesale products and services reliant on the analogue telephone network known as the PSTN – which is due to close in 2025.  The PSTN supports a number of Openreach products including ISDN 2 and ISDN 30.  We’re allowing for an initial five year notice period (2023) before we stop selling the products and allow for a two year migration period leading up to December 2025.


Being a direct Communications Partner with Openreach coupled with arrangements with key wholesale call providers, Abbey can offer very competitive rates for traditional lines including Analogue, ISDN2, ISDN30 and calls.  We would be happy to provide you with a full call analysis against your current bills free of charge.  Contact us for details.

SIP Trunks

SIP trunks (VoIP, voice over Internet) lines are rapidly replacing traditional ISDN services and offer a range of flexible services for an organisations such as:

  • they are cheaper with many call types offered free of charge
  • you can have STD (e.g. “01 & 02”) numbers from outside your area
  • they generally offer better Fraud Detection
  • disaster recovery is very flexible

Our support staff will work with you to plan a transition from traditional services and advise on the suitability of your current telephone system to support these solutions.  Most current systems (PABX’s) support SIP via a simple software upgrade.

Special Numbers

If you are looking for a special number for your business either geographic (01, 02) or non-geographic (03, 08) we have an extensive range available including offering differing services at varying call rates.  Call us to discuss the options possible and which would be suitable for you needs.
