Interesting, I shuffled some of my modem parameters around and now it's
working.  I don't know if I was doing something wrong or if the
parameters have to be in a particular order.  I had:

ats19=15 OK 'at&f1&k2' OK

and changed it to:

'at&f1&k2' OK ats19=15 OK

I wouldn't expect that to make a difference.  Thanks.
