<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Adding “no battery-reversal” did keep the call connected. I was able to press ** and heard the 2-tone confirmation from the Viking controller. It *<b>was</b>*
unlocking the door this morning on roughly every other call attempt, but now it is not unlocking it anymore for some reason. I still get the 2-tone confirmation after pressing **, the door is not unlocking, and the call stays connected until the IP phone
side hangs up or I shut/no shut the FXO port. That part doesn’t really bother me because if the IP phone user gets the call, they press **, then they just need to hang up their handset. Normally, the Viking unit is supposed to be disconnecting it after unlocking
it. Also, I tried adding “supervisory disconnect anytone”, but that didn’t make any difference. I’m going to do some more tests and check back with TAC too.<o:p></o:p></span></p>

up because it is sensing that the answer supervision signal (reversed voltage) went away (that’s the “normal_battery” part).</span><o:p></o:p></p>
