Everything else transfers to your team. **Can it hand a call to a live agent?** The agent can transfer the call to a person. A blind transfer hands the call over at once. A warm transfer lets the agent speak to the person first. You decide in the workflow when each one happens. **Can it make outbound follow-up calls?** Yes. The same agent places outbound calls, including from a call list. **Can I keep my existing number?** Yes. Bring your own number over a SIP trunk, or buy a Speko number in the console. Calls over your own SIP trunk add no telephony charge from Speko. **What does a call center overflow agent cost?** A call costs $0.09 per minute on Speko infrastructure across speech-to-text, the language model and text-to-speech. A Speko phone number adds the carrier's charge plus 20%, at least $0.01 per minute inbound. A 3 minute inbound call on a Speko number is from $0.30. Signup includes $10 in credit.
