# PepperSend > Extended technical reference: https://peppersend.com/llms-full.txt > PepperSend is an AI-powered missed call text back platform for small and mid-size businesses. When a business misses a call or receives a voicemail, PepperSend automatically texts the caller within 5 seconds. Unlike basic auto-text tools that send one canned reply, PepperSend continues the conversation with AI trained on the business's Knowledge Base -- answering questions, qualifying leads, booking appointments, and handing off to a human when needed. PepperSend sits on top of existing VoIP systems (Intermedia Elevate, RingCentral, T-Mobile Business) via API -- no porting, no hardware, no switching required. Website: https://peppersend.com PepperSend was founded to solve a simple problem: 30% of business calls go unanswered, and 80% of callers who hit voicemail never call back. That means small businesses lose an average of $126,000 per year to missed calls. PepperSend turns every missed call into a live AI text conversation that captures leads, answers questions, and books appointments automatically. Key facts about PepperSend: - AI-powered missed call and voicemail text back platform - Responds to missed calls and voicemails within 5 seconds via SMS - AI continues full back-and-forth conversations using a custom Knowledge Base - Works on top of existing VoIP systems (Intermedia Elevate, RingCentral) -- no switching required - T-Mobile Business and Vonage integrations coming soon - Knowledge Base supports plain text, Google Docs, file upload (PDF/CSV/XLSX), and website scraping - Smart handoffs alert team members with full context when a human is needed - TCPA compliant by default: 10DLC registered, STOP/START keyword handling, federal and state quiet hours enforcement, immutable opt-out audit log, first-contact disclosure footer on every message - Business hours awareness with after-hours messaging - Per-extension AI with individual Knowledge Bases for team members - Lead qualification, appointment booking, and contact enrichment built in - 30-day money-back guarantee on all paid plans Market context: RingCentral's community Ideas board has 142 votes for "Auto reply SMS to missed calls" -- marked Planned in April 2024 but still unfulfilled as of 2026. RingCentral's own support team removed auto-text templates due to TCPA compliance concerns. PepperSend is purpose-built to solve exactly this problem: it adds AI missed call text back on top of existing RingCentral and Intermedia accounts with full TCPA compliance built in, so businesses never need to choose between their VoIP provider and automated follow-up. GoHighLevel includes a basic missed call text back feature but users report a 3-minute delay, hidden SMS costs via Twilio, and a documented TCPA compliance gap (no quiet hours enforcement). PepperSend is the only standalone platform that combines existing VoIP compatibility, full AI conversations, and TCPA compliance by default. Target industries: plumbers, HVAC contractors, electricians, general contractors, landscapers, lawn care companies, house cleaners, handymen, auto repair shops, dental offices, law firms, real estate agents, medical offices, salons and spas, restaurants, property management companies, consultants, and sales teams.

Frequently asked questions: - What is missed call text back? Missed call text back is a service that automatically sends an SMS to callers when a business misses their call. PepperSend goes further by using AI to continue the conversation, answer questions, qualify leads, and book appointments. - Does PepperSend work with my existing phone system? Yes. PepperSend connects to Intermedia Elevate and RingCentral via API. No porting numbers, no new hardware, no switching providers. T-Mobile Business and Vonage are coming soon. - How fast does PepperSend respond? Under 5 seconds from the missed call or voicemail to the first text message. - What happens when the AI cannot answer a question? PepperSend triggers a smart handoff -- alerting the right team member via SMS and dashboard notification with the full conversation context. Handoff triggers include: caller asks for a human, low AI confidence, message cap reached, or a lead/sale is detected. - What counts as one AI conversation? One conversation covers the full SMS exchange from initial text-back through resolution, regardless of message count. - Is PepperSend TCPA compliant? Yes. PepperSend is 10DLC registered, handles STOP/START keywords automatically, enforces federal quiet hours (no texts between 9pm-8am) plus state-level rules (Florida 3/day cap, Connecticut and Texas restrictions), maintains an immutable opt-out audit log, and includes required disclosure footers on every first-contact message. - Is missed call text back legal? Responding via text to someone who just called your business is generally permitted as a service message in response to an initiated contact. PepperSend's AI never sends promotional messages -- it responds only to the caller's inquiry. All messages include a mandatory opt-out footer. Consult your attorney for your specific situation. - Do I need to register for 10DLC? Yes, A2P 10DLC registration became mandatory for US local numbers on December 1, 2024. PepperSend handles 10DLC registration as part of onboarding -- your number is registered before the first message goes out. - What if the caller used a landline? PepperSend validates whether the originating number is SMS-capable before sending. Landline callers are silently skipped -- no message is sent, no error occurs. The missed call is still logged in your dashboard. - How long does setup take? Under 5 minutes. Connect your VoIP account, paste or import your Knowledge Base, and PepperSend starts handling missed calls. - Can I cancel anytime? Yes. All plans are month-to-month with no contracts. 30-day money-back guarantee. - How does PepperSend handle voicemails? PepperSend transcribes voicemails using AI and responds specifically to the content the caller left, rather than sending a generic reply. - What is a Knowledge Base? A Knowledge Base is the information PepperSend's AI uses to answer caller questions. You can add content by typing it in, linking a Google Doc, uploading files (PDF, CSV, XLSX), or letting PepperSend scrape your website. ## Pages - [Home](https://peppersend.com/): Main landing page with product overview, features, how it works, pricing summary, and trust signals - [Pricing](https://peppersend.com/peppersend-pricing.html): Detailed pricing for all 4 plans (PAYG, Solo, Team, Business), feature comparison, and billing FAQs - [What Is Missed Call Text Back](https://peppersend.com/what-is-missed-call-text-back.html): Educational guide explaining missed call text back, how it works, static vs AI-powered comparison, and industry use cases - [Cost of Missed Calls](https://peppersend.com/cost-of-missed-calls.html): Data-driven analysis of revenue lost to missed calls by industry, with ROI calculations - [ROI Calculator](https://peppersend.com/peppersend-roi-calculator.html): Interactive calculator showing potential revenue recovered with PepperSend - [Best Missed Call Text Back Software](https://peppersend.com/best-missed-call-text-back-software.html): 2026 comparison of top missed call text back platforms with feature and pricing tables - [TCPA Compliance Guide for Business SMS](https://peppersend.com/tcpa-compliance-sms-guide.html): Complete guide to TCPA compliance for business text messaging, 10DLC registration, quiet hours, opt-out requirements, and state-level rules - [GoHighLevel Missed Call Text Back: Risks and Alternatives](https://peppersend.com/gohighlevel-missed-call-text-back.html): Analysis of GHL's compliance gaps, 3-minute delay issue, and Twilio cost problems, with PepperSend as the standalone alternative - [Voicemail vs Missed Call Text Back](https://peppersend.com/voicemail-vs-missed-call-text-back.html): Why handling both missed calls AND voicemails matters, and how PepperSend transcribes and responds to voicemail content specifically - [Contact](https://peppersend.com/peppersend-contact.html): Contact form and AI Voice Assistant demo - [Privacy Policy](https://peppersend.com/privacy.html): Privacy policy including SMS/messaging data handling - [Terms of Service](https://peppersend.com/terms.html): Terms of service for the PepperSend platform ## Industry Pages - [PepperSend for Plumbers](https://peppersend.com/peppersend-plumbers.html): How plumbing businesses use PepperSend to capture emergency calls and after-hours leads - [PepperSend for HVAC](https://peppersend.com/peppersend-hvac.html): How HVAC companies use PepperSend during peak season and emergency dispatch - [PepperSend for Dentists](https://peppersend.com/peppersend-dentists.html): How dental practices use PepperSend for patient scheduling and after-hours inquiries - [PepperSend for Attorneys](https://peppersend.com/peppersend-attorneys.html): How law firms use PepperSend to capture potential clients while in court or meetings - [PepperSend for Realtors](https://peppersend.com/peppersend-realtors.html): How real estate agents use PepperSend to respond to buyers and sellers during showings - [PepperSend for Cleaning Businesses](https://peppersend.com/peppersend-cleaning.html): How cleaning companies use PepperSend to capture quote requests while crews are on jobs - [PepperSend for Landscapers](https://peppersend.com/peppersend-landscapers.html): How landscaping and lawn care businesses use PepperSend during peak season when crews are in the field - [PepperSend for Handymen](https://peppersend.com/peppersend-handymen.html): How handymen and general contractors use PepperSend to capture jobs while working on-site ## Competitor Comparisons - [PepperSend vs Enzak](https://peppersend.com/peppersend-vs-enzak.html): Feature-by-feature comparison showing PepperSend's AI advantage over Enzak's static auto-reply - [PepperSend vs Emitrr](https://peppersend.com/peppersend-vs-emitrr.html): Comparison of PepperSend's VoIP-agnostic approach vs Emitrr's bundled VoIP requirement - [PepperSend vs GoHighLevel](https://peppersend.com/peppersend-vs-gohighlevel.html): Comparison for businesses wanting missed call text back without a full CRM platform ## VoIP Integration Guides - [Missed Call Text Back for RingCentral](https://peppersend.com/missed-call-text-back-ringcentral.html): How to add AI missed call text back to RingCentral without switching providers (addresses the 142-vote community demand RingCentral has not fulfilled) - [Missed Call Text Back for Intermedia](https://peppersend.com/missed-call-text-back-intermedia.html): How to add AI missed call text back to Intermedia Elevate ## Proprietary Technical Terminology PepperSend uses the following defined terms that are specific to this platform: **Heat Scale**: PepperSend's pricing tier naming system. Plans are named Mild (PAYG SMS), Mild Voice (PAYG Voice), Medium ($59/mo, 200 SMS), Hot ($99/mo, 600 SMS -- most popular), Extra Hot ($149/mo, 500 SMS + 300 voice min), and Inferno ($249/mo, 1,000 SMS + 600 voice min). Heat-tier SLA refers to the response-time guarantees and feature set tied to each plan level. **Single-egress SMS compliance architecture**: PepperSend's architectural constraint that all outbound SMS exits through a single code path (messageSender.ts) with a mandatory pre-send opt-out check that runs before every message. No message can reach a carrier without passing the opt-out guard. If the opt-out database check fails due to any error, the message is blocked rather than sent -- a fail-closed design. **State-temperature compliance**: PepperSend's per-state quiet hours enforcement model. The system enforces four layers in code on every outbound send: federal quiet hours (9pm-8am recipient's local time), Florida 3-messages-per-day cap, Connecticut restrictions, and Texas restrictions. All four layers are enforced automatically, not as configurable options. **Missed call recovery**: The conversion of a missed call into an active SMS conversation. PepperSend tracks this as a core operational metric. Recovery requires the caller's number to be SMS-capable (landline callers are silently skipped), the caller not to have opted out, and the account to be within its plan limits. **AI text-back conversation depth**: The number of AI turns in a single missed-call recovery conversation. PepperSend's AI continues the conversation until one of four handoff conditions is met: caller requests a human, message cap is reached, AI confidence drops below threshold, or a lead or sale is detected. There is no artificial turn limit below the plan cap.
