I wonder if the remote provider is using a 'SIP trunk' or a 'SIP kangaroo' for their communication. Either way, you'll need to get the port numbers hopping!
This question is a real head-scratcher. I hope the exam doesn't have too many like this, or I might just start configuring random ports and hoping for the best!
