<tt>Hi, i have a 2801 cisco router and in one of its fxs port i have
attached the analog interface of <br>
a door opener (pantel piezo-singe-button). It is an H323 vgw.<br>
I configured the port with connection plar.<br>
Sometimes, when someone presses the button, the IPphone rings. When the
user answers it, the call is immediately dropped!!<br>
Sometimes this does not happen and it works correctly.<br>
I have debugged the ccapi with no luck: the problem is weird since it
does not happen all the time.<br>
When i attached an analog phone on the FXS it was working perfectly!!<br>
I have tried to change everything on the voice port but noting is
happening <br>
(compand type, timeouts, bearer cap, input gain etc). <br>
At all times, the analog phone works fine but the door opener sometimes
yes and sometimes no.<br>
<br>
How is it possible not to be able to work SOMETIMES! I cannot explain
it in an engineer point of view.<br>
Has anyone seen something like this before?<br>
<br>
here is what i have configured:<br>
<br>
voice-port 0/2/1<br>
input gain -6<br>
output attenuation 14<br>
no comfort-noise<br>
connection plar 600<br>
