Vexen Group

AI call center in Serbia

Voice Vexen is AI call center software by Vexen Group, Belgrade, Serbia. AI agents answer and make phone calls in Serbian or any language you choose and, during the call, work in your business systems: they check and update data, fill in spreadsheets, send emails and text messages and check availability through APIs. Every call and campaign is visible in one place, and your staff can use the same phone system for their own calls.

What it does

  • Upselling: the agent calls customers and offers additional purchases.
  • Fewer returned parcels: when a parcel is not collected, the agent arranges redelivery by courier or to a parcel locker and checks the address with Google Maps.
  • Order confirmation calls.
  • Offering new services to existing customers.
  • Online shop support: finds a parcel by phone number and sends a returns link by SMS.
  • Front-desk calls: opening hours, addresses, contacts.

In numbers

  • 7,000+ calls a day handled by our AI agents
  • 10+ simultaneous calls, all at the same quality; the limit is set by the telecom operator, not the software
  • 5–15 days from contract to a working agent
  • Any language you choose

Pricing

A one-time fee for building the agent and connecting it to your systems, then a monthly license. License packages depend on the number of calls per month and the complexity of the agent.
