<p>Hello,</p>
<p>why do you set the variable cseq_diff to 1? From the module README:</p>
<p>"The CSeq difference is stored in $dlg_var(cseq_diff), be sure this variable is not overwritten via config operation."</p>
<p>A suggestion would be to test this with DBG log level, so see if the dialog module is logging something related to the CSEQ update code path. There is some log output that should be visible.<br>
</p>
<p>Cheers,</p>
<p>Henning</p>

I’m unsure if I’ve missed something silly around the track_cseq_updates flag, or if app_ruby somehow isn’t interacting with the dialog module when running uac_auth to trigger the increment?</div>
