HI everyone, What is the recommended approach to integrating a VAPI agent into a customer's existing phone system? We are thinking of getting a VAPI number and then having them forward the calls they want answered by AI to the VAPI number, as it seems the easiest to do. The one drawback to this seems to be that we would not have the customer's phone number on the caller id. What are the other options are there and any pros / cons of each approach, would be very helpful. Thanks in advance

Port the customer’s number to Vapi for full control and caller ID, or integrate Vapi with their existing phone provider like Twilio via API for seamless routing..

Thanks for your reply. How long does porting typically take - Twiiio docs say 2 - 4 weeks! Would the customer have to port it into VAPI or can I do it on their behalf? The other option is to integrate VAPI with their current SIP provider - is there a more detailed guide on how to do this? As I am fairly new to SIP etc.

Yes it takes 2 - 4 weeks
