no i c ouldnt , becasue i am using a pabx in the middle between vapi and my sip trunk server , so i was able to configure the inbound routes , based on extensions , so i create an extension inside my pabx , and connect it to a phone number provided from my sip porivder , and then i use this extension to create a phone number inside vapi. it works perfectly for the inbound calls, but now i think i need to do the eaxct same thing for outbound routes.
