How many inbound calls can you have in parallel if you have just one phone number? If it is just one, is there any way to have redundancy?

<@742302893385842739>
With just one phone number, you can typically handle one inbound call at a time. However, to achieve redundancy and handle multiple inbound calls simultaneously, you can set up multiple phone numbers and distribute the calls among them. This way, if one line is busy, the next call can be routed to another available number. Additionally, you can implement call queuing or use a cloud-based PBX system that allows for handling multiple calls on a single number through call waiting and distribution features. If you need more specific information on how to set this up with VAPI, please let me know, and I can assist you further.

There is a message in one of the examples saying there can be up to 10 concurrent calls. So if I have just one phone number, I can still have 10 calls at the same time?

<@742302893385842739> By default, you’re allowed to handle a maximum of 10 simultaneous calls (inbound and outbound combined). This limit isn’t tied to the number of users but to the total concurrent calls. If you need to increase this limit, you’ll need to purchase additional concurrent lines from the dashboard.

Here’s how to purchase more concurrent lines:
- Go to the VAPI Dashboard.
- Look at the bottom left corner of the dashboard.
- Click on the green button labeled with your organization’s name.
- Select the Billing option.
- On the Billing page, click on Add-ons, and you’ll see the option to purchase more concurrent lines.
