I’d like to know which entity will send te 100- Trying response?
Is it the transport layer?
The transaction layer if one has not been sent prior to the 80ms timer firing.
Or can we send a 100 response with the method ServerInviteSession:provisional()?
You can certainly send a 100 to the Stack, I'll let the DUM experts chime in on anything in DUM that might prevent this from just working. I would expect that you could, however.
