<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The code is mostly fine here ... but I'm not entirely sure it's something that makes sense to go into Asterisk. This is the kind of change that I would make (and have made many times) while debugging an issue, but just throw away when I'm done. If we did it for this function, why not every API call in Asterisk? Why not _every_ function?
Most cases where we have it today in the upstream code are for the purposes of resource tracking. For example, track the real file/func/line that allocated memory.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Because in so many cases, the hangup is a critical issue and we need to know why this happened and who issued it. I think it's important. Otherwise I would have thrown this away too, like many other debugging patches...</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">For consistency, I think most other instances of this do it in the order of file, func, line.
Also, most code uses __PRETTY_FUNCTION__ instead of __func__. I don't know what the difference is off of the top of my head though.</pre>
