Switchvox - Distinctive Ringtones

If you have Switchvox version 5.x on an appliance with a FAX license, you will need to re-apply a new FAX license after you update to version 6.x. There is no purchase necessary, you just need to re-register for faxing under 6.0. 

Once you have updated:

1. Open Tools > Digium Addon Products

2. Select Fax from the dropdown

3. Fill out the registration form

At that point, you'll be able to send and receive faxes again as you did under version 5.x.
