Hi, i been trying to use my number in VAPI. I have tested my twilio account and it could make the call to PSTN number successfully. However i am trying to use a Singapore number as outbound caller ID, i am not able to buy a number on Twilio as they do not have Singapore number for purchase on the platform but i have verified my number on Twilio account i gotten the documentation from Twilio that includes following steps: 1. Create SIP trunking on Twilio and whitelist the IP address 2. Configure my PBX/SIP Device to Send Outbound Calls via the Trunk 3. Initiate call via VAPI i have managed to get my phone verified on Signalwire as well as creating a SIP trunk on Signalwire. Can i check in this case, do i still need Twilio as a "middle-man"? or can i link Signal Wire and link the trunking to VAPI directly? if yes then how do i configure it and find the credentials to fill as per VAPI integrations?

Depending on your PBX system, you may always need some kind of "Middle-man" as you put it, although I really dislike the term. However, if your PBX is the owner of the number and the outbound calls - you've selected the most expensive middle-man option possible. If you'd like, please DM me and I'll show a much more reasonable option.

Let me solve this for you. Connect me here or via DM. Let's set up a meeting over meet.
