You can keep your established business number while an AI phone assistant handles a defined share of incoming calls. You need a supported route from your existing connection to the assistant, together with a tested way back. Whether straightforward forwarding or a phone-system integration makes sense depends on your connection and the job the assistant must do.
That matters when the number is already on vans, invoices and your regular customers’ contact lists. Changing every reference before trying a new reception workflow creates unnecessary work. Start by documenting the connection you have. This guide covers routing and acceptance; our AI phone assistant selection guide covers the broader provider decision.
Map the call path you use today
Follow one incoming call from the customer to the person who answers. Which number is dialled? Does the call enter through the network operator, a cloud phone system or a mobile phone? Do several devices ring together? When does voicemail take over? Who has permission to change those settings? Resolve these questions before ordering an integration.
Map the busy case separately. With call waiting enabled, someone may hear ringing even while your colleague is already on another call. “The AI answers the next caller when we are busy” is therefore a requirement to test on your actual connection. A successful call to a quiet office does not prove that the routing works during a busy lunchtime.
Record the account holder, operator, service plan, phone-system administrator and responsible person inside the business. Keep credentials in secure administration rather than in the routing diagram. Give an installer the access needed for the task. Sharing an employee’s personal password makes later changes and access removal harder to manage.
Decide exactly when the assistant should answer
Unconditional forwarding sends every incoming call down the new path. Conditional handling lets your team continue to answer directly, with the assistant taking over after an agreed wait, in a supported busy state or during specified opening-hour rules. These are different operating choices. Choose the one that fits the first use case.
| Routing choice | Check before release |
|---|---|
| Immediate forwarding | Should every caller reach AI, including an existing customer with an urgent question about current work? |
| Takeover after ringing | How long does the customer wait in total, and could voicemail answer first? |
| Takeover when busy | What does the phone system report during a second call or when call waiting is enabled? |
| Scheduled routing | Who maintains holidays and temporary absences, and when does the normal route resume? |
Swisscom’s business landline guidance describes several forwarding arrangements. Confirm which arrangements your particular service supports. Avoid applying keypad commands copied from another connection’s instructions without checking their relevance to your installation.
Separate forwarding from phone-system integration
Forwarding passes a call to a destination number. SIP or a direct phone-system integration can provide a different technical route. That alone does not establish better quality or lower costs. Simple forwarding may be a sensible starting point for a small reception team. More involved reception rules may require additional integration and transfer capabilities.
Ask for a diagram showing every station in the proposed chain. Mark where AI responses are produced, where conversation information is stored and which component initiates a transfer. Ask which component can be disconnected or replaced during a problem. Someone who did not install the service should still be able to understand how a caller reaches the business.
Arrange a change window for work on a live system and name someone who will be available inside the company. Trying several configurations during normal call traffic is a poor way to discover their consequences. Save the previous state so that restoration does not rely on the installer’s memory or a browser tab left open on a laptop.
Make sure a human transfer cannot loop
A common failure is visible in the diagram: your public number forwards to AI, and AI then calls that same public number when a customer asks for a person. The call returns to the assistant. Verify a separate, reachable transfer destination and what that destination does when nobody answers.
Define what “handover” means in the proposed service. Does it connect the ongoing call? Does a colleague receive context before accepting? Does it create a callback task instead? These outcomes set different expectations. A customer should not hear a promise of an immediate connection when the actual outcome will be a note in somebody’s inbox.
Caller-number presentation also needs testing. Can your colleague reliably call the customer back after a forwarded call? Which number appears on the receiving device? How are withheld numbers handled? A displayed telephone number does not establish someone’s identity. Keep your caller-verification rules for confidential customer information.
Review waiting time alongside connection charges
The customer experiences the whole sequence: your devices ringing, forwarding, the assistant’s greeting and possibly another ringing phase during transfer. Measure from the first ring in the acceptance test. A quick assistant behind a long initial delay can still feel slow to the caller, particularly when the final answer is a request to leave a callback number.
Request separate information on telephone connections, forwarding, AI usage and transfers to staff. Swisscom’s forwarding guidance notes that connection charges can depend on the subscription. Budget against your own contract. A forwarding feature with no activation fee does not establish that every forwarded conversation is free.
Agree how abandoned calls, unanswered transfers and overlapping conversations appear in the usage report. You can then compare the first invoice with known test cases. That is much easier than attempting to reconstruct unexplained charges at the end of a month when several settings have already changed.
Run eight acceptance calls before opening the route
Test normal answering, extended ringing, a busy line, a withheld number, a second simultaneous caller, a successful staff transfer, an unanswered transfer and a disabled assistant. Make the calls from an independent connection. Internal extension calls can follow a different route from customers calling your published number.
Write the expected result for every case: which device rings, which greeting the caller hears, which note is created and who owns the next action. A callback task without a recipient is unfinished work. If a result differs from the agreed behaviour, keep that route disabled until the discrepancy has been resolved and retested.
Keep a restoration path your team can actually use
Name the person authorised to change forwarding in ordinary operation. Leave a short instruction that makes sense even when the installer is unavailable. Prove it with an actual call: disable the assistant, call the public number again and confirm that the previous reception route is working. Treat a screenshot of a setting as supporting evidence, not as the complete test.
Start with a limited call type and a controlled operating period. Record adjustments to waiting times and transfer destinations separately. Once the connection map is ready, the Business Check for an AI phone assistant can establish which routing arrangement fits your company and what its acceptance checks must cover.
Check a future handover using a real package. The guide to changing AI provider with a data export describes a limited reconstruction using sources, rules, interfaces and unfinished cases.
FAQ
Do I have to change telephone operator?
Not necessarily. First check whether your current connection supports the intended route. Changing operator should be a justified decision rather than an assumption carried over from a demonstration.
Do I need SIP integration to get started?
That depends on the connection, phone system and transfer requirements. Forwarding may suit a limited inbound workflow; more involved arrangements need review with your telephony administrator.
Can forwarding operate only during holidays?
If your service supports the required schedule. Record start, end and the person responsible. Afterwards, call from an external connection to confirm that the ordinary route has resumed.
