SIP Trunks
Migrating from ISDN to SIP for unparalleled agility and scaling.
The next big change in telecoms is here
Companies will inevitably have to migrate from ISDN (Integrated Services Digital Network) to SIP (Session Initiation Protocol) by 2025 to stay operational. From this date it’s all IP or nothing.
Since 2020, you haven’t been able to order ISDN on the Openreach network and are encouraged to order SIP, so it is best to make this change now.
What is SIP Trunking?
Future-proof your business with the direct replacement for ISDN
SIP acts as a direct ISDN replacement – and is well known for its cost savings. With SIP, businesses can enjoy having the appearance of nationwide customer coverage, even if their office isn’t physically located in that particular region. Best of all, SIP Trunking offers excellent resiliency in the event of a disaster, which is a key feature for any business continuity plan – meaning your phone lines can stay on, even during a crisis.
Planning for a successful migration
The overall transfer process is simple. We will assess the suitability of your current infrastructure and whether your internet connection offers enough bandwidth to cope with adding voice data via SIP Trunking on to your network.
