[cisco-voip] Cisco VOIP and fire alarm phone lines

[JASON BURWELL]

You may want to check up on NFPA72 Fire Alarm Code, 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.

Does anyone know if Cisco has any recommendations they officially make
on supporting analog telephony devices like fire alarm panels?
 
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.
 
The security vendors and the OEM manufacturers are saying "we don't
recommend VOIP for alarm lines"
 
Our management is saying that surely Cisco supports this, and with the
correct configuration, they can make this happen.
 
I'm looking for some official Cisco guidance (links to design guide
statements, etc) 
that might break the deadlock, and either allow me to prove to the
vendors and OEMs that VOIP is indeed a stable technology
or, allow Cisco the graceful way of saying "it's best not to do that"
 
Anyone got anything to offer?
 
I'd imagine that there's a fair number of folks who've just decided not
to use VOIP for this purpose- 
That's just not the decision here though..and I'm not the policymaker on
that level.
