<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">If the Viking is giving you its confirmation tone after you dial **, then clearly it is successfully receiving and interpreting the
DTMF from the gateway. So I think your intermittent door operation is an issue with the Viking itself or with the door hardware.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">I did kind of have suspicions about the Viking’s power supply. If the Viking is underpowered then that could explain why the FXO was
misdetecting battery reversal whenever the Viking “did something” (i.e. increased power draw). And it could also explain the present issue.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">You’re using separate power supplies for the Viking and for the door hardware, right? That is the way the Viking manual shows it’s
to be done. But it wouldn’t be the first time I’ve seen door security installers fail to take into account the current capacity of a power supply.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I went through all 10 impedance values (shut/no shut after each one) and got mixed results doing a few test calls on each one. Even leaving it at
600r (default) will sometimes work and not work. The call *<b>ALWAYS</b>* connects no matter what the impedance value is, , but the ** during the call intermittently works to unlock the door. At first, I thought it was about every 2 to 3 attempts. But,
then I could get 3 in a row to work, then I could go 5 attempts without it unlocking. Very random. I’ve tried various values for input gain and output attenuation in case it was either too faint or too hot for the Viking unit’s sensitivity. Didn’t make
a difference.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" 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>

Devices” to see if that will shed some light on what’s going on.<o:p></o:p></span></p>
