I'm wondering if I could use only Vapi without any other integration like Twilio and etc. to do outbound calling. It says that I exceeded amount of outbound calls and I still have around 900 minutes of free trial. But when I try to initiate HTTPS request to call, it says it can't do outbound calling.

Hi there! 👋 I wasn't able to determine the exact cause of your specific HTTPS request error without seeing the error message details. However, I can definitely help explain Vapi's outbound calling capabilities and the limitations that might be causing your "exceeded amount of outbound calls" error. Yes, you can use Vapi for outbound calling without integrations like Twilio, but there are some important limitations to be aware of: ## Free Trial Limitations The most likely reason you're seeing the "exceeded amount of outbound calls" error is due to Vapi's free trial limitations: 1. **Daily Call Limit**: When using Vapi-provided numbers, you can only make a maximum of 10 outbound calls per day, regardless of how many free trial minutes you have remaining. [According to Vapi's documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1343965987070021763), this is a hard limit for free telephony numbers. 2. **Geographic Restrictions**: Vapi's free telephony numbers can only be used to call US and Canada numbers. [As stated in Vapi's documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336713212233515089), "you can only call US and Canada numbers" with Vapi-provided numbers. 3. **Concurrency Limits**: There's a default limit of 10 simultaneous calls (combining both inbound and outbound). [According to Vapi's billing documentation](https://docs.vapi.ai/billing/billing-limits), exceeding this limit causes new requests to be rejected until existing calls finish. ## Troubleshooting Steps If you're still encountering issues with your HTTPS request, here are some things to check: 1. **Check if you've reached the daily limit**: Verify if you've already made 10 outbound calls today with your Vapi number. 2. **Verify the destination number**: Ensure you're calling a US or Canada number if using Vapi's free telephony.

Can i pay to do outbound calls from your platform?

Hi there! 👋 Yes, you can definitely pay to make outbound calls from the Vapi platform! While I don't have all the specific pricing details for removing particular limitations, here's what I found about Vapi's paid options for outbound calling: ## Paid Options Available 1. **Platform Fee**: Vapi charges a platform fee of $0.05 per minute for calls, prorated to the second [according to Vapi's documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336010280819359845). 2. **Phone Numbers**: You can purchase phone numbers from Vapi for $2 per month [as mentioned in Vapi's documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336232411096285264). 3. **Concurrent Call Limits**: By default, you're limited to 10 concurrent calls (both inbound and outbound combined). To handle more than this, you can purchase additional concurrent lines through the dashboard [according to Vapi's documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1341760956732276736). 4. **Bypassing Daily Call Limits**: The 10 outbound calls per day limit applies specifically to Vapi's free telephony numbers. Purchasing a Twilio number and importing it into Vapi can help bypass this limitation [as noted in Vapi's documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1335339071211438160). 5. **Enterprise Plans**: For high-volume users, Vapi offers Enterprise plans that may provide cost advantages based on your specific needs [according to Vapi's documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336232411096285264). By switching to a credit-based billing system, you can "reserve more concurrent calls with Vapi and scale infinitely" [as stated in Vapi's documentation](https://docs.vapi.ai/changelog/2024/10/10). Would you like more information about any of these specific options for paid outbound calling?

Using Phone number purchased from Vapi, you can only do 10 outbound calls a day. This regulation has been imposed on us by Telephony. To make more than 10 outbound calls a day, you have to purchase your own number from Telephony (like Twilio or Vonage) and then import it to VAPI.

Is there a limit on Twilio for daily outbound calls?

No, there is no limitation on daily outbound calls on Twilio from our side unless the number is purchased from VAPI. If in case there is any limitation, you have to check with Twilio team.
