We can apply the following customizations for iPhone softphones:
-Preconfigured server settings, so the users will have to type only username and password to begin the usage
-Brand name and icon
-All codec (including G.729)
-Balance and rating display (if your server has a http API for this)
-Link to user account page or company homepage
-Callback, phone to phone, SMS and PIN recharge (if your server has a http API for this)
-Other settings and customizations
-The app can be built from the online softphone builder service and it has to be generate and published by you (we don't offer manual builds or App Store publish services)
