I would start by making sure each of the analog lines worked fine, with a regular old princess phone, if possible. Since it was working fine, and config hasn't changed, it's likely an issue with the phone lines or cabling.<div>
<br></div><div>You don't mention what type of hardware you have, but try reseating the cables, especially if you have a amphenol connector. Those tend to vibrate loose over time and cause problems like this, where calls fail but some work depending on what port is being used. <br>

<p class="MsoNormal">I have a router that I’ve utilizes FXO modules for
making calls. When I first set it up, everything worked fine. A few
months later, users started reporting to me an intermittent problem for outbound
calls. Sometimes they can make calls, but the majority of the time, they
get a fast busy signal. I compared the current router’s
configuration to when I originally saved the configuration from initial
setup. Nothing changed. Out of perhaps 10 calls made, maybe 1 of
them went through.</p>

other ones have the same config. 2857 is the number to the Unity Express.</p>

several calls to different phone numbers. The following output is just an
