I don't know about 'REPORT', but I've always used something like:

  set log +connect +chat
  set dial "ABORT BUSY ABORT NO\\sCARRIER ABORT NO\\sDIAL TIMEOUT 5 \"\" \
    ATZ OK-ATZ-OK ATE0Q0 OK-AT-OK \\dATDT\ \T TIMEOUT 60 CONNECT \\c \\n"

where the \\c \\n catches data till newline after the CONNECT, eg:

Dec  7 01:58:42 gaia ppp[6018]: tun0: Chat: Dial attempt 1
