Hi Michael,
 
<quote>For calls in the 1.0 environment that generated a INTERSP_INCOMING CDR
record, what would the CDR record for the same calls look like in the
1.1 environment? If the answer is that it would be a MEETME_INCOMING CDR
record, is there anything in the CDR that would tell us that the call
was interSP?</quote>
In 1.1, this would have MEETME_INCOMING in 1.1 if the call was going to a meetme
bridge.  Since InterSP, you can see different values for callerServiceProviderand calleeServiceProvider. for example callerSP ATT and calleeSP BT.

In 1.1, these would be DIRECTDIAL. Since IntersP, you will see different values for callerServiceProviderand  and calleeServiceProvider.
