[SR-Users] Using PSTN as "fallback"

[Alexandru Covalschi]

it depends on which PBX you use for media relay and which codes when no
user available does it return.
What I'd suggest is to check if call is coming not from PSTN (if it comes
from PSTN - it's for sure must be routed to PBX) and if TRUE, then first
send call to PBX and if answer is not 180/183 200 etc. (you can catch that
in a specific failure_route) route calls back to PSTN.
