I don't recall the section. Unless it has recently changed, I am almost
certain at least the primary line has to be a dedicated POTS line direct
from the Telco. I know the secondary line can be shared if used in conjunction
with an RJ31X but do not recall if there are any PBX restrictions on
it.</FONT></SPAN></DIV>

<DIV><SPAN class=419584519-04112009><FONT face=Arial size=2>Does anyone know if
Cisco has any recommendations they officially make on supporting analog
telephony devices like fire alarm panels?</FONT></SPAN></DIV>
<DIV><SPAN class=419584519-04112009><FONT face=Arial

<DIV><SPAN class=419584519-04112009><FONT face=Arial size=2>We use ATAs for
supplying dialtone to fire alarm dialers, and we're getting issues with
some panels getting "comm trouble" issues, and data not getting to the
monitoring company correctly.</FONT></SPAN></DIV>

<DIV><SPAN class=419584519-04112009><FONT face=Arial size=2>The security vendors
and the OEM manufacturers are saying "we don't recommend VOIP for alarm
lines"</FONT></SPAN></DIV>

<DIV><SPAN class=419584519-04112009><FONT face=Arial size=2>Our management is
saying that surely Cisco supports this, and with the correct configuration, they
can make this happen.</FONT></SPAN></DIV>

<DIV><SPAN class=419584519-04112009><FONT face=Arial size=2>I'm looking for some
official Cisco guidance (links to design guide statements, etc)
</FONT></SPAN></DIV>
<DIV><SPAN class=419584519-04112009><FONT face=Arial size=2>that might break the
deadlock, and either allow me to prove to the vendors and OEMs that VOIP is
indeed a stable technology</FONT></SPAN></DIV>
<DIV><SPAN class=419584519-04112009><FONT face=Arial size=2>or, allow Cisco the
graceful way of saying "it's best not to do that"</FONT></SPAN></DIV>

<DIV><SPAN class=419584519-04112009><FONT face=Arial size=2>I'd imagine that
there's a fair number of folks who've just decided not to use VOIP for this
purpose- </FONT></SPAN></DIV>
<DIV><SPAN class=419584519-04112009><FONT face=Arial size=2>That's just not the
decision here though..and I'm not the policymaker on that
