A dial gap is the configured pause between one call ending and the next dialing in an auto-dial session: 6-10 seconds for real selling, enough to save the outcome and breathe.
Definitions checked 2 September 2026.
The dial gap is the one setting in an auto dialer that shapes the whole day. Too short and the caller is still typing the remark when the next number is ringing, so outcomes stop being saved by mid-morning and the list becomes a blur of calls nobody can account for. Too long and the between-call drift returns: a glance at WhatsApp, a sip of tea, and the afternoon disappears in gaps.
Six to ten seconds is where most selling teams settle: enough to tap a status, type a few words and set a follow-up on the after-call sheet, not enough to pick up another task. Teams logging detailed notes are better served by pausing the session for that one call than by stretching the gap for all of them. Related settings live beside it: which SIM dials, whether speaker and mic default on for hands-free sessions, and what counts as a completed call (any outgoing call, or only one that lasted 5, 10 or 30 seconds, so a cut call does not mark a lead done).
These are per-phone choices, set once. In RMDialer, which we make, the gap, the SIM, the audio defaults and the completion rule are the four settings of an auto dial session, and the linked guide explains what each one changes and the values that work for Indian calling teams.

What it means
Dial gap
The configured pause between one call ending and the next dialing in an auto-dial session: 6-10 seconds for real selling, enough to save the outcome and breathe.
Software that dials phone numbers from a list automatically, one after another, so the caller never types a number and only does the talking. Also searched as automatic call dialer, automatic phone dialer or auto calling app: same tool, same category.
An auto dialer that dials exactly one number per free agent, the moment their previous call ends. Every answered call meets a human instantly, so there are no abandoned calls.
The total minutes a caller spends in actual conversation per day: the irreducible core of calling work that no dialer can compress, and the honest ceiling on daily call counts.
The one-line note saved the moment a call ends (“wants the bigger model, deciding Sunday”). The remark is what makes the NEXT call a continuation instead of a restart.

Questions
What do people ask about dial gap?
What is a good gap between auto-dialed calls?
Six to ten seconds for sales calling: enough to save the status, a remark and the follow-up, not enough to drift. Pause the session for the rare call that needs longer notes.
What happens during the dial gap?
The after-call sheet is open: the caller taps the outcome, adds a remark and sets the next follow-up. When the gap ends the next number in the list is dialed automatically.
What is an auto dialer app?
An auto dialer app calls a list of phone numbers one after another so the caller never types a number. On Android, an app like RMDialer runs the session on the phone itself using the SIM already in it: you pick a list from Excel, a Google Sheet, an API or assigned leads, press start, and the app dials each number in turn while you mark the outcome between calls.
Does RMDialer work on iPhone?
Yes. There is an iPhone app as well as the Android one, and it carries every feature except the native call log: leads, statuses, remarks, follow-up reminders, WhatsApp, templates, clients and team sync all work on iOS. Apple opens the call log to no app, so calls made on an iPhone are not recorded into the history by themselves, and only Android lets RMDialer become the phone app that answers with the customer on screen. The iPhone app is free on the App Store for iOS 17 or newer. The Web CRM works in any browser, including Safari.
How does an auto dialer work on a mobile phone?
The app becomes the phone's dialer, reads a list you give it and places each call over the SIM the same way you would by hand, only without the typing. After each call it waits a few seconds (the gap you set), shows a two-tap outcome sheet, then dials the next number. Numbers that did not answer can be rung again in a fresh session later.
Which is the best auto dialer app for Android in India?
For small and mid-sized Indian teams the best fit is a SIM-based auto dialer that runs on the phones they already own, because customers answer normal mobile numbers and there is no per-minute bill. RMDialer is that kind: the dialer is the phone app, the lead CRM, WhatsApp automation and team reports are in the same price, and the basic dialer is free with no login.
Can I auto dial numbers from an Excel sheet?
Yes. Save the sheet as Excel or CSV with a mobile number column (name and any other columns are optional), import it in the app, and start a session. The dialer calls the rows in order and lets you mark each outcome. The same works from a Google Sheet, which can also be connected as a live source so new rows import themselves.
What is a good gap between auto-dialled calls?
Five to ten seconds. That is enough to save the outcome of the last call and glance at the next lead's details without breaking rhythm. Set it longer, 15 to 20 seconds, for teams that write a proper remark after every call, and shorter for confirmation or reminder campaigns where the script is fixed.
What is the difference between a power dialer and a predictive dialer?
A power dialer calls one number at a time for one agent and waits for that call to end, so every answered call has a person ready. A predictive dialer calls several numbers at once and connects the ones that answer to whichever agent is free, which needs a call-centre server and causes dropped "silent" calls. Mobile auto dialers like RMDialer are power dialers on a SIM.
Can an auto dialer skip busy numbers and retry later?
In RMDialer the caller can skip any number during a session. For retries, switch on Call again if not answered: each missed person gets a limited number of extra rings at a pause you pick, without holding up the rest of the list. You can also filter the busy and unanswered numbers and start a fresh session later, ideally at a different hour, without re-importing the sheet.
Is an auto dialer legal in India?
Yes, for calling your own leads and customers. An auto dialer is only a faster way to place normal SIM calls, so the same rules apply as for manual calls: do not call numbers registered on the national DND list with promotional offers, honour opt-outs, and follow TRAI's rules for commercial communication. Calls to people who enquired with you, existing customers and service calls are routine.
Why do customers not answer calls from virtual numbers?
Because caller ID apps and phone dialers increasingly flag pooled virtual and VoIP numbers as spam or business calls, and because the same virtual number is often used for many campaigns. A real mobile number from a local SIM looks like a person calling, which is why SIM-based dialers report higher connect rates in India.
How many calls should a telecaller make per day?
Set the target from your own first week rather than a number from elsewhere: count dials, connected calls and saved outcomes per person, then raise it gradually. Connected conversations and outcomes matter more than dials. An auto dialer removes the dead time between calls, finding the number and typing notes, so the same person reaches more people without working longer.
How can I import leads from Facebook lead ads into a dialer?
Connect the Google Sheet that Facebook writes leads into as a lead source. Rows are checked on a schedule you set, every 30 minutes by default, then de-duplicated and tagged with the source, so the enquiry reaches a rep's calling queue the same hour instead of waiting in a spreadsheet until someone exports it. Connect the same sheet under Live Sheets in the Web CRM to share new rows across your callers in turn.
Can leads from JustDial and IndiaMART be called automatically?
Yes. Export or connect the portal's lead list (most portals email or expose leads by sheet or API), let the app import new enquiries on a schedule, and set the fresh leads to auto dial first. Speed to lead is what wins portal enquiries: the first supplier to call usually gets the order.

“Telecaller app for Android that my staff actually use. Enquiry list is assigned to each telecaller, the auto dialer calls it from their own SIM, and test ride bookings come to me live. Punjabi interface for the girls at the desk. Price is honest, everything included, no per-user surprises.”
“We needed an auto dialer app that works on our own MTN and Airtel lines, not a call centre subscription in dollars. RMDialer runs on the phones my agents already have, dials the enquiry list, and the WhatsApp follow-up goes out after every call. Calls still go out on the SIM when data drops, and the notes sync once we are back on the network.”

“We looked for telecalling software for a nine-person loan team and every quote came with cloud seats and per-minute bills. RMDialer telecalling software runs on the callers' own Jio SIMs: the lead list dials itself, the remark goes on the number, and I get dials, connects and talk time per caller every evening. Cost is one flat price per user.”
KIKavita IyerOperations head · Loan DSAChennai
“Earlier I was dialling 80 to 100 portal leads a day by hand from Excel. With RMDialer auto dialer app I import the sheet, press start and it calls one by one from my own Jio SIM. Between calls I mark Interested or Site visit in two taps and the follow-up rings me on time. Closed 3 flats last month from leads I would have forgotten.”
“We tried two telecalling CRM software before this and my counsellors stopped filling them within a week. RMDialer is the phone app itself, so every admission enquiry gets logged whether they like it or not. The auto WhatsApp after call sends the fee structure by itself. I see all 4 counsellors' calls on the web CRM every evening.”
