Can I please know the phone number limits that I can have on my vapi account? I am planning to have more than 1000 phone numbers. And can I use same webhook for all of these phone numbers to create transient assistants on the fly ?

@Conv3ction Absolutely, I'd be happy to help with that! On Vapi, you can certainly have a large number of phone numbers associated with your account. However, for specific limits such as having more than 1000 phone numbers, it would be best to check the latest guidelines and policies directly from Vapi, as these can vary based on your account type and any changes in their terms of service. Regarding your second question, yes, you can use the same webhook for all of your phone numbers to create transient assistants on the fly. This allows you to manage multiple numbers efficiently and handle incoming calls through a centralized logic defined in your webhook. If you need detailed information on the limits or assistance with setting up your phone numbers and webhook, please ask support for more info on this. They can provide you with the most current and detailed guidance for your specific needs.

@Shubham Bajaj can you please confirm the limits and my webhook approach? Will this work out?

@Conv3ction you have 10 simultaneous calls limit which means you can only make total of 10 inbound and outbound calls at the same time on your account irrespective of phone numbers your purchase. Now to make total of 1k calls irrespective of inbound and outbound you have to purchase more concurrent lines.

@Shubham Bajaj Thank you for mentioning the concurrency limit. For suppose, if i buy 1000 lines then will i be able to use those among 1000 different phone numbers on same vapi account using the SAME webhook url on all phone numbers for spawning transient assistants on the fly for Inbound Calls?

Do let me know if you require further help!!

Can you please answer my query? @Shubham Bajaj

Yes

As Bryant mentioned what you have asked for is possible and same was answered using ✅ emoji by me. Do you anything else apart from this @Conv3ction ?

Thank you but following parts of my question still remain unanswered: - Can we add more than 1000 phone numbers from twilio for suppose to a single vapi account? - If i have an inbound call setup and given that I have purchased 1000 lines making my concurrency limit 1000 instead of the regular 10, does using a single webhook (typically done by setting server URL on vapi’s organisation level) on 1000 DIFFERENT phone numbers works seamlessly? - Does creating transient assistants on the fly add a delay when answering the call in the inbound setup, if yes then how much?

> Can we add more than 1000 phone numbers from twilio for suppose to a single vapi account? Yes you can add we don't have any problem with it, but don't know about twilio. > If i have an inbound call setup and given that I have purchased 1000 lines making my concurrency limit 1000 instead of the regular 10, does using a single webhook (typically done by setting server URL on vapi’s organisation level) on 1000 DIFFERENT phone numbers works seamlessly? Yeah system works smoothly because you have access to three key pieces of information: 1. Call ID 2. Phone number the call was made on 3. Assistant ID > Does creating transient assistants on the fly add a delay when answering the call in the inbound setup, if yes then how much? No, it won't add any extra delay. By default, telephony allows a buffer of 7.5 seconds to assign the assistant for each call. So, there's no added extra latency.

Thanks a lot!
