In a scenario where there is:
- A Asterisk VoIP server (provided to you)
- A phone extension connected to the Asterisk server (provided to you)
You should build an Android APP that connects to the Asterisk Server and is able to do the following:
A) Receiving a GSM Call and Making a VoIP CALL
1) Automatically answer phone calls
2) Take GSM Audio call and create a voip IAX2 protocol call to a voip server
3) The app should receive the audio from the GSM call, encode it and send to the voip server
4) The app should receive the audio from the VOIP call, encode it and send to the GSM call
B) Receiving a VoIP Call and Making a GSM CALL
- The APP should be listening to a "mqtt" topic on a server and receive instruction on what to do.
- If the instruction is to "PlaceCall", it should receive the destination number and:
1) It should establish a GSM call to the destination
2) Execute the same steps A2, A3 and A4
Deliverable
- The Android app mentioned above
- An Asterisk configuration to: 1) receive the call and redirect to an extension and 2) receive a call from the extension and redirect the call to the Android APP
Generic Notes:
- The app should be Android Native
- The backend should run on Linux Ubuntu 18.04 (you can only install system packages that are distributed within the Ubuntu official packages - all other packages must be installed within the project).
- You should work over slack (not Freelancer chat)
Milestones:
- 10% on start after signing NDA
- 50% on first full test (no exception): all features must work (even if with bugs)
- 40% on full delivery
