There are circumstances in which IAX2 calls are rejected with no notice on the console that a call was even attempted. This does not fix the binding-related issue referred to in the linked issue, but the goal is to print out a log message when this code path is hit, for visibility.
This is a recurring issue that surfaces often, hence the push to get something in (e.g. from debugging, with an added NOTICE):
