I need a two platform dialer app which will be integrated with our voip switch.
The minimum functions are as below:
*Pop up - irrespective if in app or not,
*Choose between Voip dialer or GSM call when calling out
*Dialer - VOIP
*Select favourites from my call list
*Custom help page
*Account autoconnection to SIP
*Speakerphone mute and hold
*Background / multitasking support
*Dialer tab for making calls (2-Leg Callback Service)
*Signup page / remove / register , linked to our billing system (API supported)
*A call history of VOIP and GSM calls, CDR from our billing system
*Recharge credit via our billing system
*Automatically add DID to settings and set as CLIP, our softswitch has APi for it.
If you've done a similar project before, let me see the phone and we modify according to it.
