<p>We've been running a ccm setup for about 5 years now, many versions.. we've always used ata186s for faxes and modems.. We recently had a tech refresh of the system after a lease ended and we can't get the modems to work. Actually there is only 1 modem we care about. The one for the security system. We've never needed to give it a dedicated pots line and would prefer to not go that route. We are fully aware the ata186 doesn't support modem passthrough but its always worked in the past.</p>
<p> </p>
<p>We're using PRI lines with 2811 routers for the pstn interface. Everything is setup right, the modem does answer but the call drops about 30 seconds later on its own. Well we think on its own, we're not sure if its just the security company software timing out, they obviously have very little information about their side…</p>
<p> </p>
<p>Is anyone using a 2800 series router with modem passthrough combined with ATA186 adapters? I'd love to know your config for the combination of hardware.</p>
<p> </p>
<p>Thanks,</p>
