There are 2 million ISDN lines in the UK which must be converted to SIP or hosted applications before the entire ISDN network is withdrawn in 2025.
If your business are still using ISDN and haven’t migrated away by 2025 they will be without a phone line. If your customers are moving office they should consider SIP so they don’t have to switch over nearer 2025. Plus, when BT stops selling new lines next year, they will have no option but to go the SIP or hosted route.
We help with the migration of moving from ISDN to SIP trunks easily and with out your worry of downtime!
