SIP Trunking FAQs
SIP Trunking replaces the traditional phone line (ISDN or analogue) and typically uses the internet to connect your on-premises phone system (eg PBX) to the PSTN.
In 2017 Openreach announced that they are turning off the old analogue based PSTN in 2025. PSTN telephone lines include ISDN which many businesses have, these could be ISDN2 (BRI) or ISDN30 (PRI). Additional information can be found on BT’s website.
