@Vapi what kind of ipbx are you guys using for "Bring your own number" I am based in France, and we have this wonderful regulatory body which put some new regulation around outbound calls. With that twilio vonage and friends are unable to help - as they're not able to provide outbound numbers which are in the range we need, so we're going to go with telecom operators directly with SIP trunking - great feature (if it works as promissed). so the most common question is how we will connect - and if we know which ipbx system will call them.

@Tancho to confirm:

You're looking to connect with VAPI's telephony system using your own carrier in France due to regulatory restrictions. French regulations require specific number ranges for outbound calls that providers like Twilio and Vonage can't provide, so you need to connect directly with telecom operators via SIP trunking. You want to know what IP-PBX system VAPI uses so you can provide this information to your telecom operator.
