Auto-Reply SMS for Missed Calls
Never let a missed call go unanswered. NumeraLoop automatically sends a personalized SMS to every caller you miss — capturing leads, setting expectations, and keeping customers engaged around the clock.
The Problem
Missed Calls Are Lost Opportunities
When a prospect calls and reaches no answer, most will not call back. They move on to a competitor. Every unanswered call is a potential customer lost — especially after business hours when no one is available to pick up.
Voicemail alone isn't enough. Most callers don't leave messages. An immediate SMS response is far more effective — it acknowledges them, provides useful information, and opens a text conversation they're already comfortable with.

The Solution
Instant SMS Responses for Every Missed Call
Configure your auto-reply message once per number, and NumeraLoop handles the rest — sending an SMS automatically every time a call goes unanswered.
Instant Trigger
Auto-reply fires the moment Twilio marks the call as missed — typically within seconds of the missed call event.
Custom Message per Number
Set a different auto-reply text for each Twilio number. Tailor the message for sales, support, scheduling, or after-hours contexts.
24/7 Automatic Coverage
Auto-reply works around the clock — evenings, weekends, and holidays — ensuring no caller ever feels ignored.
Missed Call Notifications
In addition to sending an auto-reply, NumeraLoop can notify you of each missed call via the activity log so you can follow up personally.
Conversation Starter
The auto-reply SMS opens a two-way conversation. The customer replies, and their message lands directly in your NumeraLoop inbox.
Enable/Disable Per Number
Turn auto-reply on or off for individual numbers at any time from the number settings page.
Frequently Asked Questions
What triggers an auto-reply in NumeraLoop?
Auto-reply is triggered when a call is missed on your Twilio number. NumeraLoop detects the no-answer or busy status via Twilio webhook and immediately sends a configured SMS to the caller.
Can I customize the auto-reply message per number?
Yes. Each Twilio number in NumeraLoop has its own auto-reply settings, so you can configure different messages for different numbers — a sales line, a support line, and an after-hours line can all have distinct responses.
Is auto-reply active 24/7 or only during certain hours?
Auto-reply works whenever a call is missed, regardless of the time of day. It is especially valuable after business hours when no one is available to answer.
Does auto-reply work if the caller hangs up before the call is answered?
Yes. NumeraLoop triggers auto-reply based on missed/no-answer call status from Twilio, which includes cases where the caller hangs up before anyone answers.
