AI Call Center & Voice AI Agents for Business

An AI call center is a phone operation where an AI voice agent handles conversations that would otherwise need a person or a menu system. It answers inbound calls, works out what the caller needs, replies from your own business information, takes an action such as booking an appointment or creating a lead, and transfers to a human when the situation requires it. The useful difference from a chatbot with a voice is the integration: the call updates your CRM, calendar and workflows rather than ending in a transcript nobody reads.

The call arrives on your number and your phone system routes it to the agent as a destination in the dial plan. The agent converts speech to text, works out the caller intent, decides a response using your configured knowledge and rules, and speaks back in a synthesised voice. It handles interruptions rather than talking over the caller. Where it is allowed to act, it calls your connected systems during the conversation. Where it is not, it transfers to a person and passes the context across.

Yes. FreePBX is one of the most straightforward setups to add a voice agent to, because the routing you already have is the routing that decides which calls reach the agent. In practice we add the agent as a destination, then use inbound routes, time conditions and queue overflow rules to control what it receives. You can start with out of hours only, or one menu option, and widen it later. Our FreePBX integration service covers the configuration and testing.

Yes. Asterisk is the engine underneath FreePBX and can be used directly. For most deployments a dial plan destination is enough. Where you need finer control, such as monitoring live calls, injecting audio, moving a call between contexts or building custom queue behaviour, we use the Asterisk Manager Interface and the Asterisk REST Interface to control calls programmatically. That matters when the agent has to co-operate with existing call handling rather than replace it.

Yes, and this is normally how the connection is made. The agent can register as a SIP endpoint on your PBX, effectively behaving like an extension, or be reached over a direct SIP connection from your carrier or trunk. Using a standard protocol rather than a proprietary bridge means the agent fits alongside your existing infrastructure and can be replaced later without rebuilding your telephony. Concurrency, codecs and failover are set up as part of the work.

Yes, through the CRM public API. The agent can look up a caller by number before it starts asking questions, read recent history where you allow it, and write back a new lead, a logged call, a summary, a task or a pipeline change when the call ends. We build these against platforms such as HubSpot, Salesforce, Zoho CRM, Microsoft Dynamics, Pipedrive and GoHighLevel, as custom API integrations rather than certified marketplace apps. In house systems work too when they expose an API or accept webhooks.

Yes, where the calendar or booking system is connected. The agent checks genuine availability during the call rather than promising a slot and leaving someone to sort it out later, applies your rules on duration, staff member, buffer time and notice periods, then writes the booking and sends a confirmation. It can also reschedule and cancel. If the diary tool has no API, we will say so before you commit, because a booking agent without a live calendar is not worth building.

Yes. Outbound is often where the second half of the value sits: qualifying new enquiries, following up quotes, confirming appointments, reminding customers about renewals and calling back people whose calls were missed. Outbound is also more regulated than inbound. Consent, calling hours, do not call registers, caller identification and disclosure that the caller is speaking to an automated system all apply in most jurisdictions. We build campaigns to the rules that apply to you, and the lawful basis for calling remains your responsibility.

Yes, and getting this right matters more than any other single feature. The agent transfers when it hits a trigger you have configured: an explicit request for a person, a detected complaint, low confidence that it understood, or a topic you have marked as off limits. Transfers can go to a specific extension, a queue or an on call number, warm or blind. The conversation summary goes with the call, so the person picking up does not start from nothing.

Yes, where the speech and language providers support the language to a standard worth putting in front of customers. English and Turkish are the two we work with most. Spanish, German and French are available through the same providers. Quality varies by language, by accent and by how much industry specific vocabulary the agent has to recognise, so we test on your own terminology before launch rather than assuming it works. Cost also differs by language and provider.

Yes, and this is the most common starting point. Time conditions in your phone system send calls to the agent outside working hours, at weekends or on holidays, while daytime calls continue to reach your team exactly as they do today. Out of hours callers get a real conversation instead of voicemail, and your team starts the day with qualified enquiries, booked appointments and a summary of what happened overnight.

Yes, in two ways. It can answer calls that would otherwise ring out, including queue overflow and calls during busy periods, so they are never missed in the first place. It can also be configured to call back numbers that hung up or went to voicemail, capture what the caller needed, and either book them in or create a task for your team. Every attempt is logged against the contact so nobody is called twice by accident.

Yes. Depending on what the CRM API allows and what permissions you grant, the agent can create a contact or lead, attach a call log with duration and outcome, add a written summary, update qualification fields such as budget, location or timeline, move a deal stage and create a follow up task. Writes are built with retries and idempotency keys so a network failure does not create duplicate records, and failed writes are held rather than lost.

Yes. In most cases you keep your numbers exactly where they are and change only what happens after the call arrives. There is no requirement to port numbers to a new provider or to hand your main line to a third party platform. If porting does turn out to be the cheaper or more reliable option in your situation, we will explain the trade off rather than quietly moving your telephony.

The running cost is not a single figure. It is telephony per minute, speech and model usage per minute, and usually a monthly charge per concurrent line, plus the one off build. Vendors tend to quote whichever component flatters them. We itemise telephony at published Twilio or Telnyx rates, keep platform costs and our fee visible separately, and quote the build after scoping. The calculator on this page gives you an arithmetic estimate, not a price.

Sometimes, and not always. Below roughly two hundred calls a month a human answering service usually costs less than building and running an agent, and we will show you that arithmetic instead of selling around it. Above that, the comparison shifts, particularly where calls are repetitive, arrive out of hours, or are currently missed. The honest comparison also includes the build cost and the ongoing tuning, not just the per minute rate.

Usually yes. If the system has a documented API, accepts webhooks, or can be reached safely another way, it can be connected. Custom, in house and older systems are normal work for us rather than an exception, and API integration is a service we provide independently of AI voice. Where a platform genuinely cannot be integrated without unacceptable risk or fragility, we will tell you that before you commit to anything.

It depends almost entirely on the integrations, not on the voice agent. A single inbound agent on an existing FreePBX system with one calendar connection is a matter of weeks. Multiple CRM and business system integrations, complex routing, several languages or a regulated environment take longer. We give a timeline after scoping your telephony and your systems, because a number quoted before that would be a guess dressed up as a commitment.

Yes, that is the work we do. We build the agent, the call flows, the escalation rules and the integrations into your phone system and business software, rather than reselling a hosted receptionist. We also do the unglamorous part: testing on real scenarios, monitoring, retries and the failure handling that decides whether it still works in month six. If an off the shelf tool would serve you better, we will say so.
