What are SIP trunks?
SIP Trunks (Session Initiated Protocol) are connections that link the Phone System (PBX) at your business premises to the Public Telephone Network (PSTN).
These SIP connections are delivered via an IP or Assured Broadband connection (FTTC, Leased Line Circuit) meaning call quality is reliable. There is a reduced risk of downtime during an event or disaster, which could otherwise impact your business. SIP Trunks are a great alternative or addition to Digital and traditional ISDN2 or ISDN30 channels.
Why should I change to SIP?
ISDN and PSTN as technologies are being phased out by BT. They are planned to be switched off completely by 2025. This means that customers now need to consider upgrading their system, or moving to a hosted system.
