<p class="MsoNormal"><span lang="EN-GB" style="mso-fareast-language:EN-US">as already mentioned, you do dlg_manage() for initial requests. About the corner cases – I can only think about some failures in the dialog tracking due to user agent issues right now.
In normal operation the module should track all in-dialog messages due to the internal callbacks. Daniel might be able to add something as well.<o:p></o:p></span></p>

<div>
<p class="MsoNormal" style="margin-left:35.4pt">I've been reading through the dialog module docs again, and there seems to be a discrepancy in what's suggested in the docs. In the intro, it is stated that 'To create the dialog associated with an initial INVITE
request, execute the function <span class="gmail-quote">“dlg_manage()"'</span>. Later on, in section "7.10" the following example code is provided:<o:p></o:p></p>
</div>
<div style="margin-left:30.0pt">
<p class="MsoNormal" style="margin-left:35.4pt">request_route {<br>
...<br>
if(is_method("INVITE") && !has_totag())<br>
{<br>
$dlg_ctx(timeout_route) = "DLGTIMEOUT";<br>
$dlg_ctx(timeout_bye) = 1;<br>
}<br>
dlg_manage();<br>
...<br>
}<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-left:35.4pt">In this example code, dlg_manage seems to be called for all requests, as it is not dependent on the conditional that only requests with no to-tag are to be handled.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-left:35.4pt"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-left:35.4pt">Previously, Daniel had suggested to me in person that one also run dlg_manage() for CANCELs, and in-dialog reINVITEs, BYEs and ACKs to mitigate some buggy corner cases. Is this still the case?<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-left:35.4pt">What do you guys and gals do in production? Have you had to revise how you use dlg_manage in terms of calling it for initial INVITEs only vs all requests? Thanks!<o:p></o:p></p>
