<p class=MsoNormal>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.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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…<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
