Hi Everyone,<div><br></div><div>We are using two Sangoma U100 (USB FXO) units connected to an Acer Aspire Revo (little PC running on Atom). The units work beautifully except for Monday :-)</div><div><br></div><div>It maybe a conincedence or maybe the fact that Saturday/Sunday is off and something happens where one of these U100 modules goes into sleep and that's when all the 4 Dahdi channels are lost.</div>
<div><br></div><div>So, I have been getting Monday morning calls (Tuesday today but yesterday was a day off anyhow) for the past 3 weeks complaining no inbound/outbound calls can be made through PSTN.</div><div><br></div>
<div>When I log in to the server if I do a "wanrouter hwprove" I only see one of the units. If I ask them to disconnect and reconnect the U100 that is flashing (which is the one that failed) and do "wanrouter hwprobe" now it shows again. So, I can do a wancfg_dahdi and it brings it up. Sometimes, I have to recompile the whole wanpipe. But more or less I think it's the USB that fails or it could also be the wanrouter itself that fails. </div>
<div><br></div><div>Sangoma is closed today but maybe others from here can shed some light as it also may pretain to my dahdi/asterisk settings. I know that for sure the whole wanrouter/dahdi setup goes bad if the computer is abruptly shut-down which is really stupid (always been the case with Sangoma Wanpipe) and hence there is a safe shutdown script that I put for Wanrouter which does the job if the computer is shutdown properly. I don't believe the UPS failed over the last few off days but I am looking into the logs anyhow.</div>
<div><br></div><div>I appreciate your feedback and let me know what info I can post here that may help resolve the issue (such as output from dmesg or lspci?).</div><div><br></div><div>Regards,</div>
