SMS Agent
Texts back. Books for real.
Half your customers would rather text than call. Give them an agent that answers instantly, holds the thread, and puts real appointments on your real calendar - all over SMS.

Yes please

a real reschedule, done entirely over text
NOT AUTORESPONDER TEXTS - A REAL AGENT
It reads, it answers, it actually books
Most platforms send canned confirmations. The Nixflex SMS agent holds the whole conversation: it uses the same live calendar your voice agent uses, so over text it can create, reschedule and cancel real appointments - never claiming anything the calendar didn't accept, guarded by the same engine truth gate as calls.
Its own personality per number
Each phone number carries its own SMS instructions - independent from the voice prompt, so texting tone can differ from call tone.
Remembers the conversation
Session memory keeps the thread coherent - the customer never repeats themselves mid-conversation.
Everything lands in your systems
Bookings made over SMS fire a webhook with the full conversation attached - your CRM sees text-bookings the same second they happen.
Built for platforms
Everything is API-drivable - onboard hundreds of numbers in code, each with its own instructions, live on the very next text. Auto-reply stays off until you switch it on.
No per-SMS platform fee
Nixflex adds nothing per message - delivery is billed by your own Twilio or Telnyx at their rates. (US numbers require carrier A2P registration.)
Your numbers can text back - intelligently
