Note:  The Bria softphone will not work on MaxCS 6.7.0.205 without the addition of a software patch.
This patch can be found here.

These application notes are provided for dealers who are configuring AltiGen Communication's MAXCS to work with Bria's VoIP service for iPhones.

Bria client phones can have both 3G and Wi-Fi enabled. If users are making or receiving calls while near their configured Wi-Fi access point then, Bria will use Wi-Fi for the signaling. If users are out of range of a Wi-Fi access point, or if they turn off the Wi-Fi option on the Smartphone, then Bria will use 3G signaling.
