085 or local number
A national 085 number (Dutch business number) or a local area code, such as 010, 020, 030, 040, 050, 070 or 015. The application includes an identity check.
Business telephony via the internet (VoIP) means: a fixed business number without a telephone exchange in the meter cupboard. With Slimbot you get an 085 number or local number, make calls from the browser or app, set up a menu and call forwarding, and can have an AI receptionist answer each line. All in the same account as your WhatsApp, e-mail and website chat.
CallerCan you come round this week for a leak?

To office or mobile. Set multiple numbers in order, so the caller reaches the first available colleague.
Set a line to "AI" and the AI receptionist answers in Dutch: answer questions, note messages, transfer calls.
For each conversation you can read the transcript and summary, and listen to or download the recording. You can see missed calls in one overview.
VoIP stands for Voice over IP: calling via the internet instead of via a copper telephone line. For a business, this means: your number is in the cloud, and you call with what you already have. A laptop with headset, your mobile or a fixed device that works via the internet. No telephone exchange is needed that someone has to maintain.
The big advantage for SMEs is flexibility. The number belongs to the business, not to one team member. Anyone authorised to answer can do so from the office, home or on the go. And because the call runs through software, it can also be transcribed and summarised.
Most businesses have telephony separate from the rest of their customer contact: a calling provider here, a mailbox there, WhatsApp on a phone. In Slimbot, the phone is in the same account as your team inbox. The summary of the last conversation with a customer appears in their timeline in the inbox, next to the last WhatsApp message.
We prefer to be honest upfront. With an 085 number you cannot receive SMS. A queue with hold music for incoming callers and routing based on opening hours are not currently available; for that you use the menu and forwarding numbers. And the AI receptionist speaks Dutch.
