Stay connected with your customers even when you’re on the move. The respond.io mobile app now lets you manage VoIP calls just like on the web app — all from the palm of your hand.
To access calling features, open the respond.io mobile app and tap the Calls tab — represented by a phone icon — located right after the Inbox tab at the bottom of the screen.
If the tab shows a green badge with a blinking animation, it means there are incoming calls waiting.
All incoming VoIP calls appear as cards in the Calls tab.
Each card includes:
Contact’s name and number
Assigned agent avatar
Current lifecycle stage
Two action buttons:
✅ Accept – Answer the call
❌ Decline – Reject the call
If there are no incoming calls, you’ll see an empty state with the message “No incoming calls.”
If you’re viewing a conversation with a Contact who is calling, a card will appear directly within the conversation.
Only shows for that specific contact.
Accept/Decline buttons are visible unless you’re already in another call (in which case they’re disabled).
You can make calls from two screens:
Tap the Call button (phone icon) at the top.
Choose from available VoIP numbers via the Call Menu.
If no VoIP channel is connected, the app defaults to a local line call with a warning: “Local line calls aren’t tracked in reports or history. To track this call, use VoIP instead.”
Tap the Call button next to the Contact’s number.
Choose between VoIP or Local Line options via the Call Menu.
If the Contact has no phone number saved, a “+” icon appears to let you add one.
Once a call starts, a new screen appears showing:
Contact name, avatar, and call status (e.g., Calling… or 00:26)
Call actions:
🔊 Speaker toggle
🔇 Mute toggle
❌ End Call button
You can minimize the ongoing call into a floating call bar that remains visible as you navigate the app.
Displays contact name and call duration.
Tap the bar to return to the full call screen.
Call remains active even if the app is minimized or phone is locked (unless interrupted by OS or network issues).
Calls from the same contact you’re viewing will trigger an in-app notification card.
The regular Call button is disabled during an incoming call.
Receive call alerts even when you’re outside the app.
On iOS: Grouped by contact.
On Android: Grouped by workspace, then contact.
Tapping a notification takes you to the Calls tab.
From your mobile app settings, go to:
Settings > Update notifications
Here, you can configure Call Sound Notification:
Enabled by default.
Choose who triggers the ringtone:
Contacts assigned to me and unassigned
Contacts assigned to me only
All Contacts
Call actions automatically generate event logs in the chat history:
Outgoing:
<Agent> started an outgoing VoIP call.
Contact did not answer the VoIP call.
Call ended. Duration: 01:20
Incoming:
<Agent> answered an incoming VoIP call.
You missed a VoIP call from the Contact.
Call ended. Duration: 01:20
If your admin has disabled calling, you won’t be able to place or receive calls. The Calls tab will show an empty state: “Calling isn’t available. Please contact your manager for access.”
If phone number masking is enabled for your account, phone numbers will appear as: ******-1234.
VoIP calls cannot be initiated with inactive Telnyx numbers. You’ll see an error message if attempted.
The VoIP calling feature is not supported on iOS devices in China due to restrictions on native call UI handling in China. This does not affect other regions.
Local line calls use your device’s native dialer and are not tracked in reports.
To track calls, always use a connected VoIP channel (Telnyx).
VoIP calls support mute, speaker, and call minimization for multitasking.
