Plumbing first · Other service businesses welcome
Your businesskeeps working.So does the phone.
Eva is an automated voice that answers forwarded calls in your business name, captures the enquiry and follows the urgency rules you approve. Callsign sets it up and manages it with you.
Onboarding our first Melbourne businesses now.
01 / WHAT EVA DOES
A useful answer when nobody can stop.
Configured around your approved business information, not a generic script.
Answers calls forwarded from the number customers already use.
Captures name, number, need, address and requested timing.
Answers from the services and FAQs you approve.
Uses your rules to identify calls needing an urgent response.
Sends a structured outcome after the call.
Captures a booking request without inventing a confirmed time.
02 / PLUMBING FIRST
Hot water. Blocked drains. Active leaks. Different calls need different handling.
Callsign starts with plumbing because the call flow must separate genuine urgency from a routine callback request. The same managed foundation can be configured for electrical, HVAC and other service businesses.

05 / STRAIGHT ANSWERS
Know the boundaries before you forward a call.
Is Eva a real person?
No. Eva is an automated voice configured with information approved for your business. Talk to the live demo →
Does Eva confirm bookings?
Eva captures the requested service and preferred time. A slot is only confirmed when a real calendar or job-system integration accepts it, or your team confirms it.
What happens to urgent calls?
You define the situations that should trigger an SMS or transfer. We configure and test those rules with you. Automated classification still has limits, which the demo and test process make explicit.
Do I need a new number?
No new advertised number is required. Calls forward from the business number customers already use, subject to the carrier's forwarding setup.
What does it cost?
The first five paying customers receive setup waived and pay $250 AUD per month, including 250 inbound call minutes. The service is monthly with no fixed-term lock-in.
How quickly can we go live?
We aim to go live within two working days after complete business inputs and successful test calls. Timing also depends on forwarding and vendor availability.
