In their own words
BT Global SIP
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 completely or provide outbound voice without a full replacement. Features include inbound PSTN traffic, local, regional and national outbound calls, emergency calling, number porting, and DDI reservation and allocation. BT describes integrations with Microsoft Teams, Zoom Meetings, and Cisco Webex. Global SIP Outbound is stated to be available in 73 countries, while full PSTN replacement is available in 24. A cloud self-service portal offers 24/7 ordering, provisioning, and management, with changes taking effect in real time; BT says portal access has no charge. BT also describes end-to-end security, fraud prevention, and monitoring. Its service schedule says 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.
