Re: voice calls to faxmodem (slow recovery)

      I had written earlier that if a voice call comes in to my faxmodem it
    takes a long-time to recover.  After more investigation I found out the
    modem do not generate the "NO CARRIER" message after the hangup.  I am
    enclosing the traces.  Thanks!

please show also a session trace from spool/log/ of such a
voice call... (and see below for comments in your trace) ....

why do you set you modem to class 0 (data mode again)?
