Phone Number Management
The Phone Numbers page in Topa.io makes it easy to manage and customize your numbers. Here’s how it works:
Syncing with Twilio
Step 1 — Syncing with Twilio
After connecting your Twilio account, click Sync in the Topa dashboard.
All active numbers from Twilio will appear automatically.
If you delete a number in Twilio, simply click Sync again — it will be removed from Topa.io.
💡 If you have multiple Twilio accounts connected, Topa.io will show which account each number belongs to.
Step 2 — Manage Inbound Call & SMS Handling
You’ll see two toggles for each number:
Handle Inbound Calls
Handle Inbound SMS
✅ For most users, both should remain enabled. (These settings are mainly for advanced configurations.)
If you are very familiar with Twilio, you may wish for your numbers to be handled using some custom functions in Twilio, if that is the case you can turn off the toggles and do your own SMS and Phone routing in Twilio.
Step 3 — View Inbound Activity
Inbound Calls: See all call-backs from your voicemails.
SMS Replies: View all text message responses sent to your numbers.
Step 4 — Adjust Number Settings
Click the Settings (⚙️) icon on the far right side of the number.
Inside Settings, you can choose one of the following options:
Just Hang Up – End the call immediately.
Play a Message – Type a short message to be played automatically.
Forward the Call – Redirect incoming calls to another phone number (make sure to include the country prefix).
NEW Feature - We will now announce the caller in a whisper to your destination number, the whisper will say - Voicemail Call From NAME at COMPANY
Step 5 — Enable Webhooks for Inbound Events
If you want to receive real-time notifications when someone calls or replies via SMS:
Enable Webhook for inbound events.
Topa.io will send a webhook as soon as you receive a inbound call or sms. This is particularly useful for inbound calls as you could insert this into your CRM so you can know who is calling.
Example webhook:
{
"Date": "2025-10-28",
"CallTime": "14:12:14",
"CustomerNumber": "+447534000000",
"CustomerName": "Jonny",
"Company": "",
"Email": "",
"Campaign": "ADS Campaign 1",
"InboundNumber": "+447411200000",
"Destination": "message",
"SMS Reply": ""
}Useful info: If the SMS Reply field is empty, the webhook is for a inbound call. If there is anything in that field, its a SMS reply.
Inbox Help Guide
The Topa Inbox is where all lead communication is managed. It allows you to view and respond to SMS replies and inbound calls, send messages or voicemails, and manage leads within a lightweight CRM environment.
This guide explains how the Inbox works and how to use its core features.
1. What the Inbox Shows
Every interaction from your campaigns will appear inside the Inbox.
This includes:
Inbound calls
SMS replies
Conversations started manually
Leads pushed from enrichment
Each conversation represents a single lead, and all communication history is stored in that thread.
2. Understanding the Lead Source
Each lead in the inbox includes a Source label.
The source shows how the lead first entered the inbox.
Possible sources include:
Inbound Call – The lead called back from a campaign voicemail.
SMS – The lead replied to an SMS message.
Important
The source does not change, even if the lead interacts through another channel later.
Example:
The source always reflects the original entry method.
3. AI Reply Classification
The first SMS reply from a lead is automatically analyzed by AI.
It will be categorized as one of the following:
Positive
Neutral
Negative
This helps you quickly identify interested prospects versus leads that are not interested.
CRM Automation
From the Phone Numbers page, you can configure a webhook to automatically push positive replies into your CRM.
This allows qualified leads to be automatically transferred into your sales pipeline.
4. Sending and Replying to SMS Messages
The Inbox supports two-way SMS conversations.
You can:
Reply directly to incoming messages
Continue conversations with leads
Send follow-up messages manually
Inside each conversation, you will see the complete SMS history, including:
Messages sent from campaigns
Messages sent manually
Replies from the lead
This creates a single timeline of all communication with that contact.
5. Following Up on Missed Calls
If a lead calls your number but the call is missed, the conversation will still appear in the Inbox.
You can quickly follow up by:
Opening the conversation
Clicking Send SMS
Sending a reply message
This allows you to recover leads who attempted to reach you.
6. Sending Voicemails from the Inbox
You can send a voicemail to a lead directly from the conversation thread.
To do this:
Click Send Voicemail
Type your voicemail message
Click Send
This is useful when you want to follow up with a personal voicemail during an ongoing conversation.
7. Blacklisting Leads
You can blacklist leads to prevent further outreach.
When a lead is blacklisted:
They will no longer receive SMS messages
They will no longer receive voicemail drops
Automatic Blacklisting
Any message containing "delete" will automatically trigger blacklisting.
This ensures compliance with opt-out requests.
You can also manually blacklist a lead from the conversation thread.
8. Using the Inbox as a Mini CRM
The Inbox includes basic CRM features to help organize leads.
You can:
Add notes to a conversation
Assign leads to team members
Update lead statuses
This helps your team track conversations and manage follow-ups.
9. Adding Leads Manually
You can manually add a lead to the Inbox.
Click Add Lead
Enter the lead's details
Start messaging via SMS or voicemail
This is useful for leads that come from other channels outside of campaigns.
10. Enriching Leads with B2B Data
Topa also supports B2B enrichment.
You can:
Enrich a contact to find their cellphone number
Click Start Conversation
Once started, the lead will appear in the Inbox where you can:
Send SMS messages
Drop voicemails
Continue follow-up conversations
11. White-Label and Team Access
The Inbox supports multiple users through white-label access.
Permissions work as follows:
Campaign-Based Visibility
Users can only see:
Leads generated from campaigns assigned to them
Manually Added Leads
If a user manually adds a lead:
Only users within the same user group can see that lead.
This ensures proper team-level access control when working with clients or agencies.
Summary
The Topa Inbox acts as a central communication hub and lightweight CRM for your outreach campaigns.
From one interface you can:
View inbound calls and SMS replies
Send SMS and voicemails
Manage conversations
Classify leads using AI
Assign leads to team members
Enrich and add new contacts
Control team visibility through white-label access
This allows you to manage all lead engagement from one place without needing an external messaging system.
