Hey salam!
i am beginner so bear with me  
i have implemented text chat using sockets with server side php api by getting help from tutorials.
now i want to add voice chat. Can i send udp packets from android phone to another phone for voice chat.?
i know i cannot do it directly so first i have to send that packet to php api that will be sent to second phone ?
is it right approach ? if not then tell me what should i do or please refer me some book for this purpose.
thanks in advance.

You're unlikely to be able to send packets directly from one phone to the other via a mobile network, so unless you want to limit the app to phones connected via WiFi, you'll likely need an intermediary server.

Have you thought about how to convert audio to data and back yet? That involves some interesting challenges like compression, data rate limits, quality etc.

Are you wanting to stream audio in real-time between users, or record a message, transfer it to the other users, and then play it?
