Good day,

            I would like to inform that our BSC sends ESN according the
3GPP2 “Interoperability Specification (IOS) for cdma2000 Access Network
Interfaces — Part 7 (A10 and A11 Interfaces)” (see bellow). BSC sending the
ESN refer to the protocol, if the ESN number digit less than 15, should use
0 to fill (8-bit ASCII “0” symbol is /0). 
According our analyses, your AAA server does not follow the 3GPP2
specification.
