<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I disagree (particularly since I told him to add it to UPGRADE.txt). The UPGRADE file is where people go to look for things that got added between revisions.
Say, for example, I upgraded Asterisk and ran into this problem. Where would I go look to see what changed? I'm not going to diff every .conf file to find the updates. I may read through the (somewhat poorly formatted) ChangeLog, but commit messages are hardly targeted for every system administrator.
No: you look at UPGRADE.txt. We've worked hard to get people to read it, and when something occurs that changes behaviour, you go read UPGRADE.txt to find out what it is.

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">OK. However, changing the default to make Asterisk work as it did before just makes the patch a regression bugfix. The user then just needs to upgrade without changing their configuration until Asterisk 13 comes out with the default changed for better SIP interoperability.
The description needs to be reworded to not talk about Asterisk internals and what the option does in terms a user would know about.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The change introduced in revision 413765 limits opening the media channel and sending the PROGRESS control frame only to cases, when the Progress Indication with value "Inband Info now available" is present in the SETUP ACK message. However, there are exchanges (like Ericsson/Aastra MD110 BC13 or Avaya Definity (revision unknown)), which don't send this PI in SETUP ACK, but they send regular dial tone. Now the dial tone (and any subsequent audio information until some progress indication is received from the PBX) cannot be heard. My proposed solution is to introduce a new config option. I've called it "alwayssendprogress" and it's a binary no/yes option. In the "no" status, it keeps the new behaviour in place. In the "yes" status, it restores the old one.
A better naming is possible, any proposals are welcome.
The supplied patch was tested on current V11 SVN and it seems to be working as expected.</pre>
