[cisco-voip] extra analog lines for 911 where a PRI exists - makes sense?

[Lelio Fulgenzi]

I'm confused. I'm looking for MLPP to drop a call so that 911 gets out. What does transferring to poison control or CPR have to do with anything?

Once the call is pre-empted, it's through. Isn't it?

  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...

      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?
