Re: BER Error in GSMMAP

note that sometimes GSM equipment does add some "private" fields  
which generates BER_ERROR.
At least the SMSC I'm debuggin now always sends SendRoutingInfoForSM  
with an additional field which is nowhere in no standard so a BER_ERR  
shows up. However its not Ethereals' fault.
