Add an AI assistant to your virtual PBX
A virtual PBX answers calls, routes them to extensions and records them, but it doesn't answer the caller's question. Calling AI is not a PBX: it is an AI assistant that connects to your existing virtual PBX or number and answers calls in natural Turkish. Your PBX stays; the assistant is added next to it.
The short answer
- A virtual PBX routes the call; an AI assistant talks to the caller, answers the question and finishes the job, such as a booking, an order or a ticket.
- Calling AI is not a PBX. It connects to your existing PBX and number over SIP or by call forwarding, and works with Netgsm, Verimor, Twilio and SIP-capable phone systems.
- Instead of a keypad menu, callers say what they need. When needed, or when the customer asks, the assistant transfers the call to a number on your team.
- The minutes the assistant talks come out of your package; your PBX subscription and line costs stay with your carrier.
What does a virtual PBX do?
A virtual (cloud) PBX runs a company's phone lines over the internet instead of on a box in the office. It answers with a greeting, routes callers through a keypad menu to a department or extension, applies office-hour rules and records calls.
Its job is to get the call to the right person. Answering and finishing the request is still up to a person, so the number of calls answered at once is limited by the people available. After hours or at peak times, calls go to voicemail or are missed.
PBX only, or PBX plus an assistant?
The assistant doesn't replace the PBX; it takes the part the PBX can't do:
Picking up
- Virtual PBX only
- Plays a greeting, rings a free extension
- PBX + Calling AI assistant
- Picks up in 0.8 seconds and talks to the caller
Caller's request
- Virtual PBX only
- Chosen with keypad buttons
- PBX + Calling AI assistant
- Said in the caller's own words
Finishing the job
- Virtual PBX only
- Someone books or logs it by hand
- PBX + Calling AI assistant
- Booked in your calendar, logged in your CRM
After hours
- Virtual PBX only
- Voicemail or a missed call
- PBX + Calling AI assistant
- Answers 24/7, weekends and holidays included
Peak times

- As many calls as free staff
- PBX + Calling AI assistant
- Several calls at once; 5 on ready-made packages
How does the assistant connect to your PBX?
There are two ways, and your number stays the same in both. Connect your PBX over SIP and decide with your PBX rules which calls go to the assistant, or, if your PBX doesn't support SIP, forward calls from your number to the assistant.
Calling AI works with Netgsm, Verimor and Twilio and with SIP-capable carriers and phone systems. Customers keep calling the number they know; no new number or new PBX needed.
The assistant instead of a keypad menu
With a keypad menu, callers press their way around and still wait for a person. With the assistant they say what they need, and it finishes the job or transfers the call to the right person. You can start with a single menu option that goes to the assistant.
After-hours answering and transfers
Calls after hours, at weekends and on holidays are answered: the assistant replies, takes the booking or request, and your team picks up the next day. It doesn't guess when it doesn't know; it transfers the call or logs a callback. Every call's recording and transcript stay in the panel.

How is the cost worked out?
Your PBX subscription and line costs stay with your carrier; the assistant is added on top. On the Calling AI side, the minutes the assistant talks on inbound and outbound calls are counted. Ready-made packages come with a monthly quota that also includes WhatsApp, web chat and e-mail, and every package can be tried free for 14 days. High-volume enterprise quotes start at 0.05 USD a minute.
When is a PBX enough, and when do you need an assistant?
A PBX alone may be enough
- Most calls are quick transfers to a person or department
- Call volume is low and staff can answer every call during office hours
- After-hours calls don't matter and voicemail is fine
An assistant makes the difference
- You answer the same questions every day
- You take bookings, reservations or tickets by phone
- Calls go unanswered after hours or at peak times
For most businesses the answer is both: the PBX routes, the assistant answers.
