In voice-port one needs to configure the correct companding type to avoid garbled audio on incoming calls.
Being the compand law already specified in the ISDN SETUP for incoming calls, I do not see the strict need to configure explicitely the compand-type to be A-law instead of default u-law, and think is a bug to have garbled audio in this case.
Does anyone recall such a request, I might have already raised the issue ages ago and do not remember the result.
