BT Global SIP

What BT Global SIP is

BT Global SIP provides VoIP connectivity between an on-premises phone system and the public switched telephone network. Depending on the country, it can replace PSTN/ISDN service or provide outbound voice without a full replacement. Calling features include inbound PSTN traffic, outbound local, regional, and national calls, emergency calling, number porting, and DDI reservation and allocation. BT describes integrations with Microsoft Teams, Zoom Meetings, and Cisco Webex for organisations connecting collaboration platforms to their voice service. Availability varies by service: BT says Global SIP Outbound is available in 73 countries and full PSTN replacement in 24. A cloud self-service portal provides 24/7 access to order, provision, and manage Global SIP, with changes taking effect in real time; BT says the portal has no charge. BT also describes end-to-end security, fraud prevention, and monitoring across its voice solutions. Its service schedule states that Global SIP is not PCI DSS compliant and should not carry payment card traffic. Pricing is on request, with charges specified in the customer order. The service is aimed at global organisations seeking to consolidate voice and data networks and connect collaboration platforms.
