Android modem + microphone + speaker

I am using i.mx6 dual and currently trying to integrate a modem using Android. In the end I want to be able to make/receive calls. The documentation I find is tricky for a person with not so much experience with hardware.

 

The modem I am using is SIM7000E and I am able to connect to the internet and make calls but I don't understand how I should add a microphone and a speaker(2 speakers actually 1 loud). Of course the modem has the capability to connect speaker and microphone but adding them directly to the modem will not make the accessible from Android.

 

So how is this possible? Should I connect the mic to i.mx6 I2S? Is there an example that I can study?
