[cisco-voip] Emergency Calling from VoIP Remote Sites

[Cristobal Priego]

If you have local PRIs or POTs lines on those remote sites. They can  
call 911, the address and phone number that the 911 dispatcher is  
going to see will be the BTN fot the pri and the address associates to  
it. I don't know how many erls do you have but at least this is how we  
have configured a customer with 5000 phones and multiple locations
