<p style="margin: 10px 0 0 0"> <span class="diff-html-changed" style="background-color: #d6f0ff;">Before writing a new feature for Asterisk, there are multiple things to consider.</span> </p>
<ul style="margin: 10px 0 0 0">
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Is the feature general purpose enough that it is appropriate for all Asterisk consumers?</span> </li>
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Is the feature appropriate for the next major version release?</span> </li>
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">How can I help reviewers of the feature verify its correctness?</span> </li>

<p style="margin: 10px 0 0 0"> <span class="diff-html-changed" style="background-color: #d6f0ff;">Whether or not a new feature is appropriate for inclusion in Asterisk is a tricky question. If you're considering adding a new feature to Asterisk, you obviously find it useful! However, not everyone uses Asterisk the same way, and features added to Asterisk should be as generally applicable to everyone as possible.</span> </p>
<p style="margin: 10px 0 0 0"> <span class="diff-html-changed" style="background-color: #d6f0ff;">Some questions you should ask yourself when thinking about whether or not your feature is appropriate in Asterisk:</span> </p>
<ul style="margin: 10px 0 0 0">
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Does the new feature contain logic that is specific to an Asterisk deployment scenario?</span> </li>
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Can the new feature be implemented using Asterisk interfaces and without modifying the Asterisk source?</span> </li>
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Does the new feature change long standing Asterisk conventions?</span> </li>
</ul>
<p style="margin: 10px 0 0 0"> <span class="diff-html-changed" style="background-color: #d6f0ff;">If the answer is </span><strong><span class="diff-html-changed" style="background-color: #d6f0ff;">No</span></strong><span class="diff-html-changed" style="background-color: #d6f0ff;"> to all of the above questions, then the feature may be appropriate for Asterisk. A </span><strong><span class="diff-html-changed" style="background-color: #d6f0ff;">Yes</span></strong><span class="diff-html-changed" style="background-color: #d6f0ff;"> to any of the above questions does not invalidate the new feature, but it may mean that discussion on the </span><a href="http://lists.digium.com/mailman/listinfo/asterisk-dev" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none"><span class="diff-html-changed" style="background-color: #d6f0ff;">asterisk-dev mailing list</span></a><span class="diff-html-changed" style="background-color: #d6f0ff;"> is appropriate before submitting the patch to the issue tracker.

<p style="margin: 10px 0 0 0"> <span class="diff-html-changed" style="background-color: #d6f0ff;">If a new feature changes the architecture of Asterisk or has a particularly large impact on core functionality, the preference is to have that new feature released in a Standard release.

However, in order to enable/disable gateway mode, chan_sip had to be able to maintain some rather complicated state information. This was relatively tricky, as chan_sip does not have a modular design and does not lend itself well to code changes.

<p style="margin: 10px 0 0 0"> <span class="diff-html-changed" style="background-color: #d6f0ff;">There are many ways of testing a new feature. The simplest, and most common, is the 'developer test', where the developer of a new feature verifies that it works on their development machine. While this is good, as the complexity of a new feature increases, the more difficult it becomes to verify that the new feature (a) works as intended and (b) does not adversely impact other Asterisk features.</span> </p>

<p style="margin: 10px 0 0 0"> <span class="diff-html-changed" style="background-color: #d6f0ff;">Maintainability is a tricky proposition. When a developer writes a new feature, the implementation makes perfect sense! However, not all developers view code the same way, and even the same developer - upon revisiting code at a later date - may forget why something was implemented the way it was. These problems are compounded by code complexity, differences in coding standards, and poorly abstracted design.</span> </p>
<p style="margin: 10px 0 0 0"> <span class="diff-html-changed" style="background-color: #d6f0ff;">Making your new feature maintainable goes a long way to getting it included in Asterisk. Features that fit well within the Asterisk architecture; are easy to inspect and test; and impact as little existing code as possible are much easier to incorporate than features that are not well compartmentalized. The following are a list of questions to ask yourself when you're writing your new feature that will help in making the feature maintainable:</span> </p>
<ul style="margin: 10px 0 0 0">
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Are you following the </span><a class="confluence-link unresolved" href="#" style="color: #3b73af; text-decoration: none"><span class="diff-html-changed" style="background-color: #d6f0ff;">established Asterisk coding guidelines</span></a><span class="diff-html-changed" style="background-color: #d6f0ff;">?</span> </li>
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Are you using all of the appropriate Asterisk libraries, and are you using them for their intended purpose?</span> </li>
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Have you thought about how your code will be </span><a href="#NewFeatureGuidelines-testing" style="color: #3b73af; text-decoration: none"><span class="diff-html-changed" id="changed-diff-11" style="background-color: #d6f0ff;">tested</span></a><span class="diff-html-changed" id="changed-diff-12" style="background-color: #d6f0ff;">?</span> </li>
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Can the new feature exist in a separate </span><a class="confluence-link unresolved" href="#" style="color: #3b73af; text-decoration: none"><span class="diff-html-changed" style="background-color: #d6f0ff;">module</span></a><span class="diff-html-changed" style="background-color: #d6f0ff;">?</span> </li>
<li> <span class="diff-html-changed" style="background-color: #d6f0ff;">Are the places where the new feature interacts with existing code well understood? By that, think about:</span>
