Acrobits released the very first general SIP client on the App Store in 2009! It was our client that was the first to support push notifications (2010), calls over 3G ( 2010), Callkit (on release day in September 2016), and several other features over that same span. Acrobits has proactively worked on delivering any enhancement provided by the Apple iOS engineers before its peers. Cloud Softphone has been designed and built to allow you to choose the features that appeal most to your users. We accomplish this through Acrobits’ SDK, which provides our clients with access to the same technology used by market leaders. Need more info?? Request a demo today.
