Need an HTML5 app that can be run on a smartphone (especially iPhone v5.x+ (or iPad) to make SIP calls to a 3CX VOIP gateway server.
The source code shall be integrated into an existing HTML5 app. Configuration consists of entering a server IP address, a user ID (extension) and a password. That is all that is required by the free 3CX SIP client running as a native app on the iPhone.
NOTE TO ALL BIDDERS:
1) I am NOT looking for a native iPhone or Android app. Read the project description carefully and dont waste time by posting generic responses.
I want an HTML5 app ... NOT an iOS app.
2) Only respond if you have previous experience creating SIP/VOIP applications - otherwise please REMOVE yourself as a bidder on this project.
3) I dont want to deal with a company - i want to work only with a primary developer who is able to do this project.
