Key Features

​
Spam Management

Mark phone numbers as spam if they get flagged or face delivery issues: Purpose:
  • Prevent further issues with problematic numbers
  • Track which numbers have been marked as spam
  • Easy spammed/unmark toggles
How It Works:
  • Click “Mark Spam” button on any active phone number
  • Number status changes to Spammed with timestamp
  • Click “Unmark Spam” to restore normal status
  • Spam status is tracked with date for your records
Marking a number as spam doesn’t automatically stop billing. You must unrent the number to stop charges.

​
Unrenting Phone Numbers

When you no longer need a phone number, you can unrent it to stop billing: What Happens:
  1. Number is marked as Unrented with timestamp
  2. Billing stops from the next billing cycle
  3. Inbound and outbound agent associations are removed
  4. Number cannot be recovered after unrenting
Important:
  • Billing continues until the next billing date
  • Example: If your next billing is March 15th and you unrent on March 10th, you’ll be charged one more time on March 15th, then billing stops
  • Unrented numbers show “Stopped” status in Next Billing Date column
Check your “Next Billing Date” before unrenting to understand when charges will stop.

​
Billing Policy

​
Billing Cycle

Phone numbers are billed on a monthly recurring basis: How It Works:
  • Purchase Date - The day you purchase becomes your billing day
  • Next Billing Date - Same day next month
  • Example: Purchase on January 15th → Next billing on February 15th, March 15th, etc.
Edge Cases:
  • If purchased on the 31st, next billing is on the last day of shorter months
  • Example: Purchase on January 31st → February 28th (or 29th), March 31st, April 30th, etc.

​
Billing When Unrenting

Billing stops from the next cycle after unrenting: 
**Scenario 1: Unrent Before Billing Date**

```
Purchase Date: January 15, 2024
Current Date: February 10, 2024
Next Billing: February 15, 2024

Action: Unrent on February 10, 2024

Result:
✓ Charged on February 15, 2024 (one more cycle)
✗ No charge on March 15, 2024 (billing stopped)
```

<!-- slide -->

**Scenario 2: Unrent After Billing Date**

```
Purchase Date: January 15, 2024
Current Date: February 20, 2024  
Next Billing: March 15, 2024

Action: Unrent on February 20, 2024

Result:
✓ Charged on March 15, 2024 (one more cycle)
✗ No charge on April 15, 2024 (billing stopped)
```

<!-- slide -->

**Scenario 3: Same-Day Unrent**

```
Purchase Date: January 15, 2024
Current Date: February 15, 2024 (Billing Day)
Next Billing: March 15, 2024

Action: Unrent on February 15, 2024 (after charge)

Result:
✓ Charged on February 15, 2024 (today)
✓ Charged on March 15, 2024 (one more cycle)
✗ No charge on April 15, 2024 (billing stopped)
```
Pro Tip: To minimize charges, unrent immediately after a billing date passes rather than right before one.

​
Refund Policy

No refunds are provided for:
  • Partial months after unrenting
  • Spam-marked numbers
  • Unused calling minutes on the number
Example: 
If you unrent on March 10th but next billing is March 15th:
- You'll be charged on March 15th for the full month
- No refund for the unused days (March 15-31)

  • Consider purchasing a replacement number
  • Unrent the spam number to stop billing
Minimize costs by timing your unrentingBest Practice:
  • Check “Next Billing Date” before unrenting
  • If billing is in 2 days, consider waiting until after
  • Unrent immediately after billing date for minimal charges
Example:
Next Billing: March 15th
Current Date: March 13th

Better: Wait until March 16th to unrent
Why: Avoid paying for unused March 15-31 period
Use clear naming for agents assigned to numbersGood:
Phone 1: +9198765xxxxx
- Sales Demo Agent
- Product Inquiry Agent

Phone 2: +9198765yyyyy  
- Customer Support Agent (Inbound)
Better:
Sales Line: +9198765xxxxx
- [Outbound] Sales Demo
- [Outbound] Product Inquiry

Support Line: +9198765yyyyy
- [Inbound] 24/7 Support
