A voip call from Pierre PBX to extension 7424 on the key telephone system in Lincoln, 
Nebraska. 

A. The required entry in the Pierre Outbound Phonebook to facilitate 

origination of the call, would be 1402263742.  The call would be directed to 

the Lincoln voip’s IP address, 200.2.9.5.   

(Generally on such a call, the caller would have to dial an initial “9.”  But 

typically the PBX would not pass the initial “9” to the voip.  If the PBX did 

pass along that “9” however, its removal would have to be specified in the 

local Outbound Phonebook.)  
B. The corresponding entry in the Lincoln Inbound Phonebook to facilitate 

completion of the call would be  

1402263742  

for calls within the office at Lincoln 

1402    

for calls to the Lincoln local calling area (PSTN).
