About this app

IBC Callback automatically texts callers when you miss a call or finish one.
Missed call auto text, callback SMS after calls, call blocking, SMS auto reply and scheduled group texts, all in one app.

Driving or in a meeting? IBC Callback sends a missed call text such as "Sorry, I can't talk right now. I'll call you back soon." the moment you miss a call.
If you run a shop or handle sales or customer calls, you can automatically send your store info, bank details or business card image after every call.

▶ Callback Texts (Automatic SMS)
Turn each situation on separately and set its own message.
• Missed Call Text: sent when you miss a call
• Call Ended (Incoming) Text: sent after you finish a call you received
• Call Ended (Outgoing) Text: sent after you finish a call you made
• Unanswered Call Text: sent when the person you called doesn't pick up
• Blocked Number Text: sent to calls you block or reject
• Attach up to 3 images (MMS), and send long messages as MMS

▶ SMS Auto Reply
• Automatically reply to incoming texts
• Reply only to texts containing certain keywords (e.g. booking, location, hours)
• When someone replies STOP, the app stops texting that number

▶ Detailed Sending Options
• Same-number interval: every time, or once every 1-3 hours or 1, 7, 15 or 30 days
• Don't send on certain days or hours, such as nights and weekends
• Choose recipients: contacts only, everyone except contacts, or include/exclude a group
• Confirm before sending, notify after sending
• Do-not-text list for numbers that shouldn't get texts
• Never auto-texts your own number
• Skips senders that can't receive replies, such as short codes and alphanumeric senders

▶ Caller ID & Call Blocking
• Shows the caller's number in a pop-up when a call comes in
• Block calls before the phone rings
• Auto-reject blocked numbers after a set time
• Block a whole range by registering just the prefix
• Block all unknown numbers, with exceptions for groups, days and hours
• Add numbers straight from contacts or recent calls

▶ Group & Scheduled Texts
• Create recipient groups and send group texts
• Save frequently used messages
• Scheduled texts: send at a set date and time, or repeat weekly

▶ PC Link
• Edit blocked numbers, callback texts, groups and scheduled texts in the PC Link app (Windows, Mac)
• See incoming and missed calls on your PC, and send and receive texts
• Connect instantly by scanning the QR code on your PC screen

▶ Backup & Restore
• Back up blocked numbers, callback texts, groups, messages and schedules to a file
• Restore everything when you switch phones

▶ Great For
• Anyone who often misses calls and needs a missed call auto text
• Shops, academies, clinics, real estate, delivery and sales teams that send info after calls
• Anyone who wants to block spam and telemarketing calls
• Businesses that send group or scheduled texts to customers

▶ Permissions
IBC Callback uses the following permissions for callback texts and call blocking.
• Phone, Call logs: detect missed and ended calls, show caller ID, block numbers
• SMS/MMS: send callback texts, missed call texts and auto replies
• Contacts: show contact names, choose contact and group recipients
• Display over other apps: show the caller ID pop-up
• Notifications: sending notifications, foreground service
This information is used only to run the app's features, and is sent only to your own PC when PC Link is turned on.

▶ Notes
• Standard SMS/MMS rates from your carrier apply.
• Your carrier may limit sending if many texts go out in a short time, so set a same-number interval.
• SMS auto reply may not work if chat (RCS) is turned on in your messaging app.
