<p class="MsoNormal"><span style="color:#1F497D">I would swap the FXO connections around and check if the problem stays with the line or stays with the FXO port.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">If the problem stays with the specific FXO port, then it’s probably something with your config. Confirm trunk type is correct. I’ve had half-ring unanswerable calls when caller-id was enabled on the port but
the line didn’t actually have caller ID service. I’ve also had that sort of behaviour with fried FXO cards. Can also happen if CUCM DB replication is wonky, causing gateway registration to be messed up.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">If the problem moves when you move the line to a different port, then it’s probably something with the line. Bad connection that craps out upon loop current flowing is possible. Or there is something else sharing
the line that you don’t know about. Building security system, HVAC controller, utility meter etc. sometimes get spliced onto a line by people who don’t necessarily understand the implications of doing so. These devices often attempt to have “intelligent” line-sharing
capabilities, which tends to get confused by IOS gateway taking the line off-hook the instant it senses ringing.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Small site with 3 FXO lines in a carrier hunt. Gateway is MGCP controlled. Lines are setup loop start. Calls come in and ring to a broadcast hunt. First call comes in and rings and is answerable. Second call comes in,
Caller hears normal ringing. My users get ½ ring try to pickup but can never get the call. ½ ring will continue indefinitely.<o:p></o:p></span></p>
