Phone calls, one API request away.
Koda Voice puts click-to-call and predictive dialing behind one REST API, with supervisor monitoring and browser softphones built in. Skip the months of PBX and SIP engineering and start calling in days.
Why calling is still the hard part.
Building voice infrastructure is a project in itself
SIP trunks, PBX configuration, codecs, NAT traversal. That's months of specialist work before your team makes a single call.
Manual dialing burns most of the shift
Agents type numbers, sit through rings and no-answers, and log calls by hand. Actual talk time ends up being a fraction of the day.
Call quality is a black box
No way to listen in, coach agents mid-call, or review what was said. Quality control happens by guesswork, after the damage is done.
Two ways to call, one API.
Click-to-Call
Start a call with one HTTP request. Koda Voice rings the customer, rings your agent, and bridges them. The SIP plumbing is handled for you.
- Plugs into any CRM or internal tool via REST
- Indonesian number validation built in
- Call status streamed back as it changes
Predictive Dial System (PDS)
Dials several numbers per agent in a single round. The first to answer gets connected and the rest drop automatically, so agents move from conversation to conversation without dialing.
- Round size capped per tenant, under your control
- Lead references echoed back in every event and call record
- Abandoned calls tracked and measurable
