iPhone and Android App to play recorded message on our IVR system

This app for both iPhone and Android will allow cellphones to access the audio contents on our Asterisk IVR system. Once the phone is connected to IVR, the phone will allow user to listen to different menu selection by pressing the digits on their phone. This app is a private app for use of myself and selected customer; and free for my customers to install and use. The app should have configuration settings that includes Host, AccountID and Passcode. Once the phone is connected to the host, the caller will hear first an ‘entry’ message and then a ‘menu’. The menu will include up to 8 choices where the caller can select their desired selection using their cellphone keypad. The audio should be two ways as there is a choice to move the phone to the owners office phone if needed. The Host will be accessed using an IP (SIP to SIP Call) or URL (SIP URI). My plan is to use Asterisk Manager (AMI). If using AMI the port would be 5038 SIP URI would be something like 7124322322@[login to view URL] There might be other methods to accomplish this project and I am open to ideas you might have. But the goal is what’s in the description above. Any programing code produced should turned over to me. Please add to your bid “I am not a robot” so I know you have read these specs. I also wish for you to help me get this app on Testflight
