As far as CM would know it's still 911 weather they transfer you or not.
I wouldn't think this should be an issue.

Yes and no.

Here's the problem.

Let's say a user calls 911, and the operator transfers them to a poison
control unit or a CPR expert and it is just a local number... there is a
possibility that the MLPP would not recognize this as an emergency call
and bump it.

However, this may be an urban legend...

MLLP would take care of this, correct?

Actually, we put in a few analogs so we can dedicate circuits
for 911...

While Scott's argument makes sense, it misses the fact that most
PRIs are heavily oversubscribed.

Just wondering if anyone can help me justify ordering a couple
of analog lines for 911 service which will go into the same router and
be serviced by the same local telephone switch and likely be carried
over the same path as the PRIs. I already have two single port PRI cards
to protect against single point of failure of the PRI card. But in the
end, if the router goes down, it's down.



Anyone ever see a PRI port go down but FXO ports stay up?
