I have posted this project before and many bid without knowing what they are bidding for. If you are interested:

PLEASE WRITE A FEW LINES OF YOUR UNDERSTANDING OF WHAT THE APPS DOES.

Bids with no summary will be deleted.

We will have 2 android phones

They will be connected by a (crossover) 3.5 mm cable.

On phone 2 you will create an app that will listen to headset mic for a dial command followed by the numbers to be dialed.

This app will listen for a voice dial or dtmf dial from the headset jack and dial out the number it hears.

Examples of response

When a dial is received, issue a tone to acknowledge (*1).

when ringing begins, issue a tone (*2) .

if busy/congestion/not available (*3),

when call has been answered *4,

when call gets hung up (##),

(let me know of other possible codes that exist)

On phone 1

You will create a app which accepts SIP calls and generates dtmf or voice dial commands based on what comes in the sip header.

the sip app will register to a sip sever who will send it numbers to be dialed in the header

When the sip server sends a call, the sip app will issue dial command via the headphone speaker. (to phone 2)

if it hears a acknowledgement that the dial was received, wait

if no acknowledgement in x seconds (a variable default 20), issue a sip cause code 503 to sip client

If busy/congestion/unavailable etc issue 503

if ringing received issue sip 183

If busy/congestion/unavailable etc after ringing issue 503

If answer signaled is received , issue a success signal on sip side, I believe it is sip 200

If a hangup signal is received, issue a hangup on sip side, i believe sip 487

Sip client on phone 1 will only register to sip server when it detects that headset jack is being used.

If you can also make asterisk work as phone 1 (using chan_alsa) Please mention.
