How to determine if I have a Mindspeed VoIP module?
You can easily check this in ClientView. Click on the VoIP Resource object under Physical IMG -> Facility. On the right side check the "Module Configuration Profile". If that option has the word "Picasso" in it, then you have a Mindspeed module.
The absence of the word "Picasso" indicates that a Broadcom VoIP module is installed.
