SIP.US Cloud SIP Trunking connects an existing PBX to cloud SIP service through flexible channels, with no contracts. Its self-service control panel manages trunks, telephone numbers, provisioning, billing, and call records. Each channel includes unlimited outbound calling to the US48 states and Canada, plus unlimited inbound calling to local numbers; each concurrent incoming or outgoing call requires a channel. Call records are viewable near real time, cover today and the past year, and can be downloaded as CSV files. A searchable directory covers US and Canadian numbers, and most DIDs are provisioned instantly. Customers choose their broadband provider; G.711 calls use approximately 85kbps up/down, and G.729 is supported. Fraud controls can terminate unauthorized international calls, disable international calling, and send alerts. Inbound DID calls can route to primary and secondary IP-PBX systems or a backup PSTN number if routing fails. Supported systems include 3CX, Asterisk, Cisco, Avaya, and Grandstream, and the service can connect SIP trunks with Microsoft Teams. Availability is limited to businesses based in the United States and Canada.
