You're answering a call based on the RINGs.  And that could be part of 
the problem.  I would recommend at least changing those three 
configuration items to be:

RingsBeforeAnswer: 0
CallIDPattern: "CID: "
CallIDPattern: "DAD: "
CallIDAnswerLength: 9

However, there could be a possibility that the first call is 
disconnecting just after it presents Caller*ID and then the second call 
comes through immediately thereafter, just as the modem does ATA.  In my 
opinion this is really a problem that the modem is causing by not 
busying-out the channel/line for at least a few seconds before accepting 
another call on the same channel.  So, I'd suggest bringing that up with 
Eicon.

However, you may be able to work-around the issue by configuring 
Asterisk or the Diva server to allocate channels and/or modems in a 
"round-robin" fashion rather than always landing on the same 
channels/modems.

Thanks,

Lee.
