Lawrence,

I spent a good part of last year designing a DAA dongle for a softmodem.
Going through approvals in 15 countries was a period of ulcer development.

A soft modem will always cause more apprehension than a chipset based
modem.  Most PTT's consider softmodems to be infinitely programmable and
they worry softmodem could be configured for used in an un-approved mode.
Approvals are a mine field at best.  A softmodem definitely  increases the
problems and  time to get approvals.

To eliminate some problems do the following:

1.  If you don't have prior experience do not attempt approvals on your own.
2. Choose a testing house and/or consultant very carefully.  Ask for
references.
3.  Obtain quotes from several testing houses.
4.  Stress only approved softmodem code will be shipped to that country.
5.  Country configuration cannot be changed by user.
6.  Stress softmodem code is in EPROM or Flash which prevents user
intervention.
7.   If DAA is a dongle, dongle it must be fixed for that country. i.e.
dongle is identified by softmodem for use in that country only.
8.  Australia, France, Japan and South Africa require most attention.

Good Luck,
