SIP Trunking
SIP trunking for inbound and outbound business calls

Features
A full call platform
Click-to-Call
Start calls from your CRM or app. Your agent's phone rings first, then the call connects to the customer.
IVR builder
Build phone menus visually: greetings, key-press routing, queues and time-of-day rules.
Ring groups
Ring a team at once or in order, with fallback to voicemail, another group or an outside number.
Call recording
Record inbound and outbound calls and retrieve each recording from its call record.
Live call monitoring
See active calls in real time — who is connected, where and for how long — and step in when needed.
Anti-fraud rules
Velocity limits, spend caps and destination allow/deny lists help stop traffic pumping and runaway costs.
Call reports
Filter and group call records by date, destination or route, then export them for billing.
REST API
Order numbers, start calls and pull call records and balances straight into your own systems.
Use cases
What businesses use it for
Connect your PBX
Link an on-premise or hosted PBX to the public phone network over SIP instead of physical lines.

Handle campaigns and seasonal peaks with metered, unlimited or burst channels.
International calling
Use premium routes where call quality matters most and standard routes where cost matters most.
Calls from your software
Start calls and pull call records from your own systems with Click-to-Call and the REST API.
