When somebody calls your business number and you do not pick up — busy, after hours, driving, on a job — DunaHub sends them an SMS from your number within seconds. A lead is created in your CRM with the caller's phone and the call log, ready to follow up from the unified inbox.
The feature itself is free on every plan. Only the SMS is metered ($9 per 100 credits), same as the rest of the SMS system.
The cell phone or alternative line that incoming calls forward to. When this line does not pick up within the ring timeout, the missed-call text-back triggers.
If you have multiple people answering calls, set the forward number to a hunting group or your VoIP routing — anything that resolves to "somebody picked up" or "nobody picked up".
How long the business number rings before a call is considered missed. Configurable between 10 and 60 seconds. Most contractors set this between 20 and 25 seconds — long enough that you can answer if you are near the phone, short enough that the caller does not give up before the text fires.
The SMS sent to the caller when a call is missed. Keep it short, friendly, and personal — it lands on the caller's phone within seconds of them hanging up.
Example:
"Sorry we missed you! This is Mike from Acme HVAC. Reply here and I'll get back to you in a few minutes."
You can include placeholders like the caller's name if you keep variables shown in the editor. The message is the same for every caller, regardless of whether the call was busy, missed, or no-answer.
The SMS is sent from your business number — the same one the caller just dialed. To the caller it looks like a normal text from your shop, not a third-party tool.
The text-back itself costs 1 SMS credit per message sent. Credits are prepaid ($9 per 100 credits) because each SMS has a real carrier cost — there is no way to make this free without us absorbing it for every account.
Most contractors miss 6–8 calls per week. At the average $1,200 value of a missed service call, recovering even one job per month pays for years of SMS credits.
For every missed call:
If the caller's phone number matches an existing lead, no duplicate is created — the call is logged on the existing lead.
All inbound and outbound calls log to the lead's timeline:
This means you have a unified history per customer that includes calls and messages, instead of calls living separately from texts and email.
